Trait HeaderExt

pub trait HeaderExt: Header {
    // Provided method
    fn header(&self, id: impl AsRef<oid>) -> Result<Header, Error> { ... }
}

An extension trait with convenience functions.

Provided Methods

fn header(&self, id: impl AsRef<oid>) -> Result<Header, Error>

Like try_header(…), but flattens the Result<Option<_>> into a single Result making a non-existing object an error.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
