Struct StreamDescriptor 

pub struct StreamDescriptor {
    pub scope: StreamScope,
    pub name: String,
    pub retention: StreamRetention,
    pub head_offset: u64,
    pub tail_offset: u64,
    pub event_count: usize,
}

Public-facing descriptor for stream discovery — what an introspection surface (e.g. a future red.streams virtual table) would emit per stream.

Fields

scope: StreamScope

name: String

retention: StreamRetention

head_offset: u64

Offset of the oldest event still retained, or 0 if the stream is empty.

tail_offset: u64

Offset of the most recent event, or 0 if the stream is empty. The next append will receive tail_offset + 1.

event_count: usize

Trait Implementations

impl Clone for StreamDescriptor

fn clone(&self) -> StreamDescriptor

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StreamDescriptor

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

Formats the value using the given formatter.

impl PartialEq for StreamDescriptor

fn eq(&self, other: &StreamDescriptor) -> 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.
