Trait RawValParser

pub trait RawValParser
where
    Self: Sized,
{
    type Error: Into<Error>;

    // Required method
    fn parse(raw: Option<&OsStr>, ctx: &Ctx<'_>) -> Result<Self, Self::Error>;
}

Implement this if you want parsing the raw value into your type.

Required Associated Types

type Error: Into<Error>

Required Methods

fn parse(raw: Option<&OsStr>, ctx: &Ctx<'_>) -> Result<Self, Self::Error>

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.
