Trait ValueParser

pub trait ValueParser {
    type Value<'a>;

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

Required Associated Types

type Value<'a>

Required Methods

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

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.
