Struct rama::http::layer::header_option_value::HeaderOptionValueLayer

pub struct HeaderOptionValueLayer<T> { /* private fields */ }
Expand description

Layer which stores the Default value of type T in case the header with the given HeaderName is present and has a bool-like value.

Implementations§

§

impl<T> HeaderOptionValueLayer<T>

pub fn required(header_name: HeaderName) -> HeaderOptionValueLayer<T>
