Trait num_traits::Num
[−]
[src]
pub trait Num: Zero + One + NumOps<Self, Self> + PartialEq<Self> { type FromStrRadixErr; fn from_str_radix(
str: &str,
radix: u32
) -> Result<Self, Self::FromStrRadixErr>; }
The base trait for numeric types, covering 0 and 1 values,
comparisons, basic numeric operations, and string conversion.
Associated Types
type FromStrRadixErr
Required Methods
fn from_str_radix(str: &str, radix: u32) -> Result<Self, Self::FromStrRadixErr>
Convert from a string and radix <= 36.
Examples
use num_traits::Num; let result = <i32 as Num>::from_str_radix("27", 10); assert_eq!(result, Ok(27)); let result = <i32 as Num>::from_str_radix("foo", 10); assert!(result.is_err());
