Trait fast_float::FastFloat

pub trait FastFloat: Float {
    // Provided methods
    fn parse_float<S: AsRef<[u8]>>(s: S) -> Result<Self> { ... }
    fn parse_float_partial<S: AsRef<[u8]>>(s: S) -> Result<(Self, usize)> { ... }
}

Trait for numerical float types that can be parsed from string.

Provided Methods

fn parse_float<S: AsRef<[u8]>>(s: S) -> Result<Self>

Parse a decimal number from string into float (full).

Errors

Will return an error either if the string is not a valid decimal number. or if any characterse are left remaining unparsed.

fn parse_float_partial<S: AsRef<[u8]>>(s: S) -> Result<(Self, usize)>

Parse a decimal number from string into float (partial).

This method parses as many characters as possible and returns the resulting number along with the number of digits processed (in case of success, this number is always positive).

Errors

Will return an error either if the string doesn’t start with a valid decimal number – that is, if no zero digits were processed.

Object Safety

This trait is not object safe.
