Rust: wsd is an intuitive crate delivers What Simply Defined.

Documents

https://docs.rs/wsd

Most simple way to make http request

Get

fn test() {
    wsd::http::get("https://docs.rs/", |data| {
        println!("status = {}, data = {}", data.status(), data.text());
    });
}

Post

fn test() {
    wsd::http::post("https://docs.rs/", "{id: 100}", |data| {
        println!("status = {}, data = {}", data.status(), data.text());
    });
}

Request

 use wsd::http::*;
 fn test() {
    let mut c = Request::new(Method::POST, "https://docs.rs");
    c.gzip(true);
    c.timeout(5);
    c.header("TOKEN", "1234567890");
    c.send("{id: 100}", |data| {
        println!("Data: {}", data.text());
        println!("Headers: {:#?}", data.headers());
     });
}

Intutive File Class

Just a convenient wrapper to rust File, check the return value quickly as we did with C API, don't need to check the Result, and unwrap() etc.

Methods

File::new()
File::open()
File::read()
File::write()
File::close()
File::error()
File::path()
File::seek()
File::position()
File::length()
File::is_none()

Open flags

O_CREATE
O_TRUNCATE
O_RW
O_READ
O_WRITE
O_APPEND
O_NONBLOCK

Seek flags

SEEK_SET
SEEK_CUR
SEEK_END

Example

using wsd::fs::*;

fn test() -> i32 {
    let mut f = File::new();
    if f.open("test.txt", O_CREATE | O_RW) != 0 {
        // check the error
        println!("Error: {}", f.error());
        return -1;
    }

    let data = "Hello World!";
    let n = f.write(data);
    if n < 0 {
        // write error
    }

    f.rewind();
    let mut buf = [0; 4096];
    let n = f.read(&mut buf);
    if n > 0 {
        // success to read n bytes
    }

    // get file length
    let off = f.length();
    if off > 0 {

    }

    f.seek(256, SEEK_SET);
    f.write("more data");

    f.close();

    return 0;
}
