Struct StreamId 

pub struct StreamId {
    pub ms: u64,
    pub seq: u64,
}

A stream entry’s <ms>-<seq> identifier. The Ord derivation compares ms first then seq, which is exactly the monotonic order the protocol requires; same derivation gives Eq, Hash, and the BTreeMap key bound.

Fields

ms: u64

Unix milliseconds timestamp component.

seq: u64

Per-ms sequence number, 0-based.

Implementations

impl StreamId

pub const MIN: StreamId

The numerically smallest ID; XRANGE - start.

pub const MAX: StreamId

The numerically largest representable ID; XRANGE + end.

pub fn encode(self) -> Vec<u8>

Render as the canonical <ms>-<seq> wire form.

pub fn next(self) -> Self

Step one ID past self. Saturates at Self::MAX.

Trait Implementations

impl Clone for StreamId

fn clone(&self) -> StreamId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for StreamId

impl Debug for StreamId

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

Formats the value using the given formatter.

impl Default for StreamId

fn default() -> StreamId

Returns the “default value” for a type.

impl Eq for StreamId

impl Hash for StreamId

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for StreamId

fn cmp(&self, other: &StreamId) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for StreamId

fn eq(&self, other: &StreamId) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for StreamId

fn partial_cmp(&self, other: &StreamId) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
