Struct HistoryInfo 

pub struct HistoryInfo(pub Vec<HistoryEntry>);

A complete History-Info list in wire order.

Tuple Fields

0: Vec<HistoryEntry>

Implementations

impl HistoryInfo

pub fn from_headers(headers: &Headers) -> Option<Result<Self, HeaderError>>

Parse every History-Info row as one ordered cache.

RFC 3261 §7.3 makes repeated list-header rows equivalent to one comma-joined row. The history indices must therefore be validated across the joined value: decoding a later row by itself would incorrectly reject its first 1.1 entry for not beginning at 1.

pub fn initial(target: Uri) -> Self

Start a history at the mandatory first index.

pub fn retargeted( self, previous: Uri, next: Uri, reason: &ReasonValue, kind: TargetChangeKind, ) -> Self

Extend this UA’s history for a retargeting action.

If the received cache omitted the actual previous Request-URI, the inserted .0 entry makes that gap visible before the new .1 entry is appended.

pub fn apply_privacy( &mut self, message_privacy: bool, ) -> Result<(), HeaderError>

Apply RFC 7044 history privacy before emitting the cache.

pub fn apply_message_privacy( &mut self, headers: &Headers, ) -> Result<(), HeaderError>

Apply message-level Privacy: history or Privacy: header, plus any entry-level privacy marker, before emitting this cache.

pub fn to_bytes(&self) -> Bytes

Serialize the complete comma-separated list.

Trait Implementations

impl Clone for HistoryInfo

fn clone(&self) -> HistoryInfo

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for HistoryInfo

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for HistoryInfo

fn default() -> HistoryInfo

Returns the “default value” for a type.

impl TypedHeader for HistoryInfo

const NAME: HeaderName = HeaderName::HistoryInfo

The header this type reads.

fn decode(value: &[u8]) -> Result<Self, HeaderError>

Parse one header value. The value arrives unfolded and trimmed.

const VALIDATE_LIST: bool = false

Whether Headers::typed_all must collect and validate the complete field before yielding.

fn decode_list(value: &[u8]) -> Result<Vec<Self>, HeaderError>
