Enum PushResult 

pub enum PushResult {
    Added,
    Duplicate,
    Evicted([u8; 32]),
    DroppedZeroCapacity([u8; 32]),
}

Result of pushing a delta to the buffer.

Provides clear semantics about what happened to both the incoming delta and any evicted delta.

Variants

Added

Delta was added to the buffer without eviction.

Duplicate

Delta was a duplicate (already in buffer) - no action taken.

Evicted([u8; 32])

Delta was added, but oldest delta was evicted due to capacity. Contains the ID of the evicted delta.

DroppedZeroCapacity([u8; 32])

Delta was dropped immediately (zero capacity buffer). Contains the ID of the dropped delta.

Implementations

impl PushResult

pub fn was_added(&self) -> bool

Returns true if the delta was successfully added to the buffer.

pub fn had_data_loss(&self) -> bool

Returns true if any delta was lost (evicted or dropped).

pub fn lost_delta_id(&self) -> Option<[u8; 32]>

Returns the ID of the lost delta, if any.

Trait Implementations

impl Clone for PushResult

fn clone(&self) -> PushResult

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PushResult

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

Formats the value using the given formatter.

impl PartialEq for PushResult

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