Trait FromStringBase 

pub trait FromStringBase: Sized {
    // Required method
    fn from_string_base(base: u8, s: &str) -> Option<Self>;
}

Converts a string slice in a given base to a value.

Required Methods

fn from_string_base(base: u8, s: &str) -> Option<Self>

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".

Implementations on Foreign Types

impl FromStringBase for i8

fn from_string_base(base: u8, s: &str) -> Option<Self>

For bases up to 36, this is a wrapper over the from_str_radix functions in the standard library, for example this one. For bases from 37 through 62, which from_str_radix does not support, the digits are read from the case-sensitive large-base alphabet (see digit_from_display_byte_large), as in GMP.

Worst-case complexity

$T(n) = O(n)$

$M(n) = O(1)$

where $T$ is time, $M$ is additional memory, and $n$ is s.len().

Panics

Panics if base is less than 2 or greater than 62.

impl FromStringBase for i16
