DocHeaderEntry

Struct DocHeaderEntry 

Source
pub struct DocHeaderEntry<H: DocumentedHeader>(/* private fields */);
Expand description

Generic IntoParams implementor that produces one header parameter from a DocumentedHeader marker, calling H::name, H::description, and H::example at runtime.

You don’t usually construct this yourself — the #[get] / #[post] / etc. macros emit it inside the synthesized #[utoipa::path(params(...))] block whenever a handler signature contains a crate::Header<H> extractor or a headers(H, ...) macro argument is supplied.

The runtime-name design (a fn on DocumentedHeader, not a const) is what makes this possible: the proc-macro can’t call H::name() during expansion, but the generated params(DocHeaderEntry<H>) reaches runtime where the call resolves cheaply.

Trait Implementations§

impl<H: DocumentedHeader> IntoParams for DocHeaderEntry<H>

Source§

fn into_params( _parameter_in_provider: impl Fn() -> Option<ParameterIn>, ) -> Vec<Parameter>

Provide Vec of openapi::path::Parameters to caller. The result is used in utoipa-gen library to provide OpenAPI parameter information for the endpoint using the parameters.
