Struct StreamSequence 

pub struct StreamSequence;

Selector for the stream sequence number; see STREAM_SEQUENCE.

Trait Implementations

impl Clone for StreamSequence

fn clone(&self) -> StreamSequence

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl ContextField for StreamSequence

type Context = JetStreamContext

The per-delivery context type this key reads from.

type Value = Option<u64>

The owned value the key yields.

fn read(self, cx: &JetStreamContext) -> Option<u64>

Reads this key’s field out of src. Named apart from Field::get so a key implementing both traits stays unambiguous to call.

impl Copy for StreamSequence

impl Debug for StreamSequence

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

Formats the value using the given formatter.

impl Default for StreamSequence

fn default() -> StreamSequence

Returns the “default value” for a type.

impl Field<JetStreamContext> for StreamSequence

type Value<'a> = Option<u64>

The value read through this key, borrowed from the source for 'a.

fn get(self, cx: &JetStreamContext) -> Option<u64>

Reads this key’s field out of src.
