Trait OptionExt

pub(crate) trait OptionExt<T> {
    // Required method
    fn or_error(
        self,
        parser: &mut Parser<'_>,
        err: impl Fn(&mut Parser<'_>) -> Result<Diagnostic>,
    ) -> Result<T>;
}

Required Methods

fn or_error( self, parser: &mut Parser<'_>, err: impl Fn(&mut Parser<'_>) -> Result<Diagnostic>, ) -> Result<T>

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.
