Struct HeaderMap 

pub struct HeaderMap(pub HeaderMap);

Header map extractor that provides access to HTTP request headers.

This extractor wraps a reference to the headers of a request, providing efficient access to header values without copying the underlying data. It can be used to inspect, validate, or extract information from HTTP headers.

Examples

use tako::extractors::header_map::HeaderMap;
use tako::types::Request;

async fn handler(HeaderMap(headers): HeaderMap<'_>) {
    // Get authorization header
    if let Some(auth) = headers.get("authorization") {
        if let Ok(auth_str) = auth.to_str() {
            println!("Authorization: {}", auth_str);
        }
    }

    // Check content type
    if let Some(content_type) = headers.get("content-type") {
        println!("Content-Type: {:?}", content_type);
    }
}
