Struct HeaderRef 

pub struct HeaderRef<'a> {
    pub name: &'static str,
    pub value: Option<&'a HeaderValue>,
}

Available on crate feature zero-copy-extractors only.

Borrowed reference to a single header value, addressed by a const name.

The const-generic NAME pattern means the header name is encoded into the type — e.g. HeaderBorrowed<{ "x-trace-id" }> — but Rust does not yet allow &'static str as a const-generic. Instead we expose HeaderRef<'a> plus the helper HeaderBorrowedBy<'a, const N: usize> for static byte names.

Fields

name: &'static str

The header name that was looked up.

value: Option<&'a HeaderValue>

The borrowed value, if present.

Implementations

impl HeaderRef<'_>

pub fn as_str(&self) -> Option<&str>

Convenience to fold a HeaderRef into a string slice when the value is UTF-8.
