FieldPreferences

rama::http::proto::h3::qpack::encoding

Struct FieldPreferences 

pub struct FieldPreferences {
    pub representation: Representation,
    pub insertion: Option<InsertionPreferences>,
    pub name_huffman: Option<bool>,
    pub value_huffman: Option<bool>,
    pub never_index: bool,
}
Available on crate features http and std only.
Expand description

Choices for one field; peer limits and the caller’s sensitivity still apply.

Fields§

§representation: Representation§insertion: Option<InsertionPreferences>

Request a fresh encoder-stream insertion of this field, even when its field line stays literal. Never-index or insufficient resources skip it.

§name_huffman: Option<bool>

Force Huffman (true) or plain (false) field names; None uses connection policy.

§value_huffman: Option<bool>

Force Huffman (true) or plain (false) literal values; None uses connection policy. Encoder-stream instructions continue to use the connection’s Huffman policy.

§never_index: bool

Strengthen never-index; this cannot clear sensitivity supplied by the caller.

Implementations§

§

impl FieldPreferences

pub fn from_observed( field: &ObservedFieldRepresentation, ) -> Option<FieldPreferences>

Turn valid wire metadata into preferences for a fresh table. Static indexes are stable; dynamic indexes describe another table and are discarded. Dynamic families keep their Base side under super::FieldSectionBase::FromFieldPreferences so the native encoder can place current entries on the requested side of its Base.
