rfc7239

Parser for rfc7239 formatted Forwarded headers.

Usage

use rfc7239::parse;

// get the header value from your favorite http server library
let header_value = "for=192.0.2.60;proto=http;by=203.0.113.43,for=192.168.10.10";

for node_result in parse(header_value) {
    let node = node_result?;
    if let Some(forwarded_for) = node.forwarded_for {
        println!("Forwarded by {}", forwarded_for)
    }
}

no_std

This crate can be used in a no_std environment by disabling the default std feature.

The only impact disabling this feature has is using core::error::Error and core::net::IpAddr instead of the std variants and increasing the msrv to 1.81.
