Trait UrlArgExtractor 

pub trait UrlArgExtractor<Context, Arg>: IsProviderFor<UrlArgExtractorComponent, Context, Arg>
where
    Context: HasUrlType + HasErrorType,
{
    // Required method
    fn extract_url_arg(
        context: &Context,
        _phantom: PhantomData<Arg>,
    ) -> Result<Context::Url, Context::Error>;
}

Required Methods

fn extract_url_arg( context: &Context, _phantom: PhantomData<Arg>, ) -> Result<Context::Url, Context::Error>

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
