Function parse_usize

pub const fn parse_usize(s: &str) -> Result<usize, ParseIntError>

Parses a usize from a &str.

This returns an Err if the string would not successfully .parse() into a usize.

To parse a usize from only part of a string, you can use Parser::parse_usize.

Const stabilization

The equivalent std function, was const-stabilized in Rust 1.82.0.

Example

For an example of how to use this function, you can look at the one for u128.
