Enum StartPosition 

pub enum StartPosition {
    FromBeginning,
    LiveOnly,
    FromSeq(u64),
}

Where the fold task begins consuming the RedEX tail.

Variants

FromBeginning

Replay from the beginning of the file (seq 0). Default.

LiveOnly

Start live-only; skip backfill. Use when State is rehydrated from an external snapshot and the adapter should only see new post-open appends.

FromSeq(u64)

Start at a caller-supplied checkpoint. The fold task sees events with RedexEntry::seq >= n.

Trait Implementations

impl Clone for StartPosition

fn clone(&self) -> StartPosition

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StartPosition

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

Formats the value using the given formatter.

impl PartialEq for StartPosition

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