Struct ApplyResult 

pub struct ApplyResult {
    pub index: u64,
    pub succeeded: bool,
}

Result of applying a single log entry to the state machine

Returned by StateMachine::apply_chunk() for each entry in the chunk. Enables operations like CAS to communicate their execution result back to clients.

Fields

index: u64

Log index of the applied entry

succeeded: bool

Whether the operation succeeded

Semantics by operation type:

• CAS: true if compare succeeded and value was updated, false otherwise
• PUT/DELETE: always true (failures return Err from apply_chunk)

Implementations

impl ApplyResult

pub fn success(index: u64) -> Self

Create a successful result for the given index

pub fn failure(index: u64) -> Self

Create a failed result for the given index

Trait Implementations

impl Clone for ApplyResult

fn clone(&self) -> ApplyResult

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ApplyResult

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

Formats the value using the given formatter.

impl PartialEq for ApplyResult

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