Trait BStrParse 

pub trait BStrParse {
    // Required method
    fn parse<F: FromBStr>(&self) -> Result<F, F::Err>;
}

An extension trait for parse.

Required Methods

fn parse<F: FromBStr>(&self) -> Result<F, F::Err>

Parses this string slice into another type.

Because parse is so general, it can cause problems with type inference. As such, parse is one of the few times you’ll see the syntax affectionately known as the ‘turbofish’: ::<>. This helps the inference algorithm understand specifically which type you’re trying to parse into.

parse can parse any type that implements the FromBStr trait.

Errors

Will return Err if it’s not possible to parse this string slice into the desired type.

Examples

Basic usage

use bstr_parse::*;
let four: u32 = b"4".parse().unwrap();

assert_eq!(4, four);

Using the ‘turbofish’ instead of annotating four:

use bstr_parse::*;
let four = b"4".parse::<u32>();

assert_eq!(Ok(4), four);

Failing to parse:

use bstr_parse::*;
let nope = b"j".parse::<u32>();

assert!(nope.is_err());

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
