Trait TryParse

pub trait TryParse
where
    Self: Sized,
{
    type Err;

    // Required method
    fn try_parse(
        iter: &mut impl Iterator<Item = u8>,
    ) -> Result<Self, TryParseError<Self::Err>>;
}

Allows a type to be parsed through the try_parse, parse, try_scan and scan macros.

Required Associated Types

type Err

Error type used in the TryParseError.

Required Methods

fn try_parse( iter: &mut impl Iterator<Item = u8>, ) -> Result<Self, TryParseError<Self::Err>>

Attempts to parse the type using an u8 iterator.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
