Type Alias CowHeaderMap 

pub type CowHeaderMap = HashMap<CowHeaderName, HeaderValues>;

Header map using Cow<’static, str> keys for zero-allocation header names.

Performance

For common headers (Content-Type, Authorization, etc.), the key is a borrowed static string reference. For unknown headers, the key is an owned String. This avoids ~95% of header name allocations in typical HTTP traffic.

Example

use sentinel_agent_protocol::headers::{CowHeaderMap, HeaderValues, intern_header_name};

let mut headers = CowHeaderMap::new();
headers.insert(
    intern_header_name("content-type"),
    HeaderValues::from_iter(["application/json".to_string()])
);

Aliased Type

pub struct CowHeaderMap { /* private fields */ }
