Struct NeutralExtractor 

pub struct NeutralExtractor<ReqBody> { /* private fields */ }

Base extractor that produces an empty cache key.

This is an internal building block used by other extractors. Users should start extractor chains with Method::new() instead.

Type Parameters

• ReqBody - The HTTP request body type. Must implement hyper::body::Body with Send bounds. This parameter propagates through extractor chains to ensure type safety.

When You’ll Encounter This

You typically don’t create this directly. It appears as the innermost type in extractor chains:

use hitbox_http::extractors::{Method, path::PathExtractor};

// The full type is Path<Method<NeutralExtractor<Empty<Bytes>>>>
let extractor = Method::new().path("/users/{id}");

Implementations
