# [−][src]Trait num_traits::Num

    pub trait Num: PartialEq + Zero + One + NumOps {
        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.

## Required methods

### `fn from_str_radix(str: &str, radix: u32) -> Result<Self, Self::FromStrRadixErr>`

# 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());

## Search Tricks

Prefix searches with a type followed by a colon (e.g., `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g., `vec -> usize` or `* -> vec`)

Search multiple things at once by splitting your query with comma (e.g., `str,u8` or `String,struct:Vec,test`)
