QUESTION
In Rust, I want to use a phantom type to properly type a simple id:
...ANSWER
Answered 2021-Jun-11 at 16:12The problem with your sample lies in understanding what the trait is. And in fact it is not a type (that's why compiler asks for T: ?Sized), but a requirement for a type. Thus the solution is fairly simple: come up with a "real" type. You got it right with a struct declaration, it can be one option. But usually it's much more convenient to use associative type for that:

So, the problem is that when ajax script receives dictionary from server it gains different order:
Server sent this:
...ANSWER
Answered 2021-Jun-09 at 16:04If your object has properties that are "indexes" (numeric strings in range 0 .. 2^32-1), these properties are always enumerated is sorted numeric order. There's no way you can change that.
Have your server app return data in a more reasonable format, like an array of number-string pairs or an array of objects {id, value}. If this is not possible, convert your object to the said format on the client side, for example:
QUESTION
I have a strange issue which occurs on specific browsers and is probably something to do with the viewport (I'm a new developer so do not fully understand the correct terms).
Browsers which have the issue:
- Brave Browser
- DuckDuckGo
Browsers which don't have the issue:
- Safari
- Google Chrome
When I scroll right down to the bottom of the page, there is a small amount of whitespace which does not go away regardless of what I do.
I have:
- Added width and height of 100% to footer
- Added a min-height of 100vh
- Checked for phantom characters
- Changed the position of scripts in HTML
Where the white begins is where the screen starts to curve (on an iPhone 11).
These are snippets of my CSS code which may be useful (the footer section is the second grey line to the bottom of the black section):

I am just trying to get deals items from this amazon URL :
when I open this link in browser and write the query in console, it works:
document.querySelectorAll('div[class*="DealItem-module__dealItem_"]')
but when I try to fetch this through this phantomjs script, it seems to always returning nothing:
ANSWER
Answered 2021-May-31 at 18:23According to the documentation on the evaluate method in PhantomJS
Note: The arguments and the return value to the evaluate function must be a simple primitive object. The rule of thumb: if it can be serialized via JSON, then it is fine.
Closures, functions, DOM nodes, etc. will not work!
Instead, you should perform your length calculation inside the evaluate, then return the simple primitive length.
QUESTION
The following used to work in Sublime Text 3, but gives an error in ST4.
...ANSWER
Answered 2021-Jun-05 at 05:53That’s because in ST4, phantoms are no longer used to show build errors. They have been replaced by something called region annotations.
Sublime Text 3: Uses Inline phantoms
Sublime Text 4: Uses the so called region annotations, that appears on the far right edge of the view. This was done mainly to reduce reflow of the document (since phantoms can cause text to shift around, which results in a somewhat janky experience).
Error message: init() got an unexpected keyword argument 'hide_phantoms_only'
Coming back to this, since phantoms are no longer used in ST4 to show build errors, any phantom related arguments that the exec command used to take is also no longer valid. Hence, the error.
Currently, I don’t think there is a way to have a key binding that will close all the error annotations, though there is an open feature request to make annotations more key board friendly (& closing all annotations is a part of that issue)

Well guys, I have this script that adds the product to the cart, but I need it to work as quickly as possible, currently it’s working for about 19 seconds if you run this code, of course there are a number of factors that should be taken into account consideration, one of them is the response time of the website and everything ...

QUESTION
I'm working with Cassandra 3.x and Phantom driver (scala), and modifying my Cassandra deployment from a simple, three nodes cluster to a multi datacenter Cassandra deployment that consists of two datacenters:
Transactional - the "main" datacenter, to which all reads/writes occur (except for reads/writes done by some analytics job).
Analytics - a datacenter used for analytics purposes only. The analytics job should operate (i.e. read/write to) on this datacenter.
I configured the client on the analytics job to read/write to the analytics data-center, and all other services to read/write from the transactional data-center.
How can I check the client actually behaves as expected - and reads/writes the data to the correct data-center?
...ANSWER
Answered 2021-May-19 at 12:36The driver has an option allowing you to turn on tracking. That should allow you to see which nodes are involved with each query.
There's a short description of how to do this on the driver documentation page: https://docs.datastax.com/en/developer/java-driver/4.2/manual/core/logging/
The query logger reference API has a lot more detail on the available methods, and can even show the values of bind vars, if needed.

#[derive(Deserialize)]
struct S<'d, T>
where T: Deserialize<'d>
{
foo: T,
other_field: String
}
ANSWER
Answered 2021-May-19 at 10:08The code works if you remove the where clause completely. The derive will add a T: Deserialize<'de> bound automatically for the derived Deserialize<'de> implementation.
