kandi X-RAY | cast Summary

cast is a Go library typically used in Utilities, JSON Processing applications. cast has no bugs, it has no vulnerabilities, it has a Permissive License and it has medium support. You can download it from GitHub.

Cast is a library to convert between different go types in a consistent and easy way. Cast provides simple functions to easily convert a number to a string, an interface into a bool, etc. Cast does this intelligently when an obvious conversion is possible. It doesn’t make any attempts to guess what you meant, for example you can only convert a string to an int when it is a string representation of an int such as “8”. Cast was developed for use in [Hugo] a website engine which uses YAML, TOML or JSON for meta data.

            the Android Gradle Plugin documentation still says classpath 'com.android.tools.build:gradle:4.2.0' instead of 7.0.1.

            You need to read further down the page, to this and this. That table is only relevant for pre-7.0.0 versions.

            Is this a bug in Android Gradle Plugin 7.0.1?

            Quite possibly. Or, perhaps beyond, as the Instantiatable Lint check has a history of problems.

            If your scenario does not match one of those three August 2021 bugs, and you are in position to provide a reproducible test case, file a fresh issue! Beyond that, if a clean-and-rebuild is not clearing up your problem, you might need to simply disable the Instantiatable Lint check for the time being by adding the following to all of your build.gradle files at the application or library level (i.e. all except your project-level build.gradle):

            Overload resolution between two constructors from std::initializer_list
            Asked 2022-Feb-12 at 23:30

            ANSWER

            Answered 2022-Feb-12 at 23:30

            The wording could be clearer (which is unsurprising), but GCC and MSVC are correct here: the relevant rule ([over.ics.list]/7) checks only that

            overload resolution […] chooses a single best constructor […] to perform the initialization of an object of type X from the argument initializer list

            so the fact that the initialization of B from {1} would be ill-formed is irrelevant.

            There are several such places where implicit conversion sequences are more liberal than actual initialization, causing certain cases to be ambiguous even though some of the possibilities wouldn’t actually work. If the programmer was confused and thought one of those near misses was actually a better match, it’s a feature that the ambiguity is reported.

            Clarification on difference in ODR rules for structs in C and C++
            Asked 2021-Nov-02 at 13:15

            I am aware of how ODR, linkage, static, and extern "C" work with functions. But I am not sure about visibility of types since they cannot be declared static and there are no anonymous namespaces in C.

            In particular, I would like to know the validity of the following code if compiled as C and C++

            ANSWER

            Answered 2021-Oct-20 at 09:43

            For C. The program is valid. The only requirement that applies here is "strict aliasing rule" saying that the object can be accessed only via a l-value of a compatible type (+ a few exception described in 6.5p7).

            The compatibility of structures/unions defined in separate translation units is defined in 6.2.7p1.

            ... two structure, union, or enumerated types declared in separate translation units are compatible if their tags and members satisfy the following requirements: If one is declared with a tag, the other shall be declared with the same tag. If both are completed anywhere within their respective translation units, then the following additional requirements apply: there shall be a one-to-one correspondence between their members such that each pair of corresponding members are declared with compatible types; if one member of the pair is declared with an alignment specifier, the other is declared with an equivalent alignment specifier; and if one member of the pair is declared with a name, the other is declared with the same name. For two structures, corresponding members shall be declared in the same order. For two structures or unions, corresponding bit-fields shall have the same widths. For two enumerations, corresponding members shall have the same values.

            Therefore the structures are not compatible in the example.

            However, it is not an issue because the f object is created and accessed via locally defined type. UB would be invoked if the object was created with Foo type defined in one translation unit and accessed via other Foo type in the other translation unit:

            Simple example of Pandas ExtensionArray
            Asked 2021-Sep-20 at 00:21

            It seems to me that Pandas ExtensionArrays would be one of the cases where a simple example to get one started would really help. However, I have not found a simple enough example anywhere.

            Creating an ExtensionArray

            To create an ExtensionArray, you need to

            There is also a section in the Pandas documentation with a brief overview.

            Example implementations

            There are many examples of implementations:

            Question

            Despite having studied all of the above, I still find extension arrays difficult to understand. All of the examples have a lot of specifics and custom functionality that makes it difficult to work out what is actually necessary. I suspect many have faced a similar problem.

            I am thus asking for a simple and minimal example of a working ExtensionArray. The class should pass all the tests Pandas have provided to check that the ExtensionArray behaves as expected. I've provided an example implementation of the tests below.

            To have a concrete example, let's say I want to extend ExtensionArray to obtain an integer array that is able to hold NA values. That is essentially IntegerArray, but stripped of any actual functionality beyond the basics of ExtensionArray.

            Testing the solution

            I have used the following fixtures & tests to test the validity of the solution. These are based on the directions in the Pandas documentation
