This article mainly introduces "how to use aljabar to automatically serialize the size of the array". In the daily operation, I believe many people have doubts about how to use aljabar to automatically serialize the size of the array. Xiaobian consulted all kinds of data and sorted out a simple and easy-to-use method of operation. I hope it will be helpful to answer the question of "how to use aljabar to automatically serialize the size of the array". Next, please follow the editor to study!

Linux can use Rust to develop kernel in the future.

Josh Triplett (one of the major developers of Linux) mentioned the possibility of Rust in a speech.

But he stressed that he didn't want everyone to use Rust, he just thought that Rust could bring more possibilities to Linux.

Josh also talked to Greg Kroah-Hartman, one of the major developers of Linux, and Greg said he was willing to accept the framework used in the kernel to write activity programs in Rust.

Now that Rust is not enabled by default, even if you do "make" and "allyesconfig", people don't need to install Rust to build the kernel.

It shows the real advantages in addition to writing C, such as secure kernel API.

It seems that there is a good chance that you can use Rust to write Linux Kernel in the future.

Wasmtime-runtime that allows php, node js, rust, and C++ to run wasm directly

You can let php, node js, rust and C++ run a runtime of wasm directly.

The film "using markdown" shows the possibility of wasmtime.

It is very convenient to call wasm downloaded functions from four languages.

Lumen: Erlang VM for WebAssembly

Use rust nightly

Features include Compiler and Runtime

The main driver for developing Lumen is to edit the application procedures based on BEAM (that is, programs written with Elixir,Erlang,LFE,Alpaca, etc.) into WebAssembly modules.

The reason is that the official BEAM implementation is not compatible with the existing technology of WebAssembly, which is this part of the Emscripten editing C / C + + program.

One problem is that the implementation of VM execution bytecode in WebAssembly results in a large operation (BEAM bytecode is solved by BEAM VM and BEAM VM is executed as WASM, which is executed by the processor WebAssembly engine).

This also requires that each BEAM module be able to run from the server and be added by VM. Even though BEAM VM can be read as WASM directly, there is no simple solution to these problems.

Lumen's BEAM bytecode is run in AOT, not in JIT. This avoids the expansion of BEAM bytecode, the produced WASM module can be added directly, and there is no runtime of JIT.

Param_attrs will be confirmed in Rust version 1.39.0

People add parameters in # [feature (param_attrs)] parentheses

Fn len (

# [cfg (windows)] slice: & [U16]

# [cfg (not (windows))] slice: & [U8]

)-> usize {

Slice.len ()

}

You can write different codes according to different operating systems in the program.

In rust 1.39 nightly you can use aljabar vectors to automatically serialize groups of any size.

The program is serialized to json

Use aljabar:: {Matrix, matrix, Vector, vector}

# [test]

Fn test_serialize () {

Let v = vector! [1u32, 2,3,4,5,6,7]

Assert_eq! (

Serde_json::to_string (& v) unwrap ()

"[1, 2, 3, 4, 5, 6, 7]"

);

Let m = matrix! [

[1u32, 2]

[3u32, 4]

]

Assert_eq! (

Serde_json::to_string & m. Unwrap ()

"[[1pr 3], [2pr 4]]"

);

}

At this point, the study on "how to use aljabar to automatically serialize the size of an array" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it!
