braket | Strongly typed bra-ket notations for Rust

In LUA, I would need to read a text file from a line with a specific content to another line with a specific content. How can I do it please?

Here an example

a text file called: aaa.txt

I have a String with Tags like this

Imagine this situation.

I am unittesting a piece of code and in order to do that I passed a multiline string to a class. I have several methods to test:

i work with an exist sqlite database, and i want to display a random row from it. i followed this steps , but it display the row with the name of the column and the brakets.

this is the code i used :

Each participant is voting some numerical values to each others, and I want to write this information by agent's name.

By the following code,

I'm currently developing a parser for an old proprietary markup-like language which has to be converted to a newer standard. I'm using ANTLR 4 for that.

The structure is composed by blocks delimited by a specific starter and its relative terminator (eg. { ... }, < ... >, INPUT ... END). Inside each block, elements are specified in rows, separated by newlines; actually, only somewhere these newlines are needed to understand what code means.

For example:

I have big json array that lists out certain key value pairs. Each element in the array should look like this:

Im not finding an answer to my exact question and unable to relate similar to it as well. Here is what i have:

I checked my function on ideone.com (https://ideone.com/Z2pVQp ) because RStudio wrongfully shows unmatched braket warning signs next to line 1, 29, 34, 87 only after you saved the file.

Since the function is quite large I spare to post it all in the question section but will give you for example the lines 29 - 34 which might be the hook to this problem.
