Strongly typed HTTP Header library for Rust, built upon serde
```rust use serdeheader::fromhttpheadermap;
struct Example { contentlength: i64, contenttype: String, }
// let mut h = http::header::HeaderMap::new(); // h.insert("contentlength", "100".parse().unwrap()); // h.insert("contenttype", "application/json".parse().unwrap());
let t: Example = fromhttpheader_map(&h).unwrap();
println!("{:?}", &t) ```
