Trait StringArgExtractor 

pub trait StringArgExtractor<Context, Arg>: IsProviderFor<StringArgExtractorComponent, Context, Arg> {
    // Required method
    fn extract_string_arg(
        context: &Context,
        _phantom: PhantomData<Arg>,
    ) -> Cow<'_, str>;
}

Required Methods

fn extract_string_arg( context: &Context, _phantom: PhantomData<Arg>, ) -> Cow<'_, str>

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.
