Trait catalyzer::internals::HandlerMetadata

pub trait HandlerMetadata {
    const PATH: &'static str;
    const METHOD: Method;
}

A trait that represents a handler metadata.

They are used to store the metadata of a handler, and are automatically implemented by the #[get], #[post], etc. macros.

This trait is used internally by Catalyzer, and should not be implemented manually.

With #[get]:

#[get("/")]
fn index() {
    "Hello, world!"
}

Manual implementation:

async fn index() -> impl ::catalyzer::res::IntoRawResponse {
    "Hello, world!"
}
#[doc(hidden)]
#[repr(transparent)]
#[allow(non_camel_case_types)]
struct index_metadata;
impl ::catalyzer::internals::HandlerMetadata for index_metadata {
    const PATH: &'static str = "/";
    const METHOD: ::catalyzer::internals::Method = ::catalyzer::internals::Method::GET;
}
