Amazonite::Core::HeaderValue
Scalar (de)serialization helpers for the http-bound members of a rest protocol's request/response - a header carries plain text, so every non-String member type needs a text conversion, and unlike a body value the timestamp format depends on the binding rather than the protocol (Smithy defaults an httpHeader timestamp to http-date and an httpQuery or httpLabel one to date-time, either overridable per shape).
Class methods
A list-typed header is one header holding comma-separated values, not one header per element, so it splits rather than being read repeatedly.
Every header whose name starts with prefix (smithy.api#httpPrefixHeaders,
e.g. S3's "x-amz-meta-" user metadata), keyed by the remainder of the
name. Header names are case-insensitive on the wire, so the prefix is
matched that way too, and the key keeps the casing the service sent.
