Trait ValueParser 

pub trait ValueParser {
    type Value<'a>;

    // Required method
    fn try_parse<'input>(
        s: Span<&'input str>,
    ) -> DiagResult<Self::Value<'input>>;
}

Required Associated Types

type Value<'a>

Required Methods

fn try_parse<'input>(s: Span<&'input str>) -> DiagResult<Self::Value<'input>>

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.
