Struct openraft_memstore::TypeConfig

pub struct TypeConfig {}

Declare the type configuration for MemStore.

Trait Implementations

impl Clone for TypeConfig

fn clone(&self) -> TypeConfig

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TypeConfig

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

Formats the value using the given formatter.

impl Default for TypeConfig

fn default() -> TypeConfig

Returns the “default value” for a type.

impl Ord for TypeConfig

fn cmp(&self, other: &TypeConfig) -> 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 + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for TypeConfig

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl PartialOrd for TypeConfig

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

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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

Returns the last applied log id which is recorded in state machine, and the last applied membership config.

async fn delete_conflict_logs_since( &mut self, log_id: LogId<MemNodeId> ) -> Result<(), StorageError<MemNodeId>>

Delete conflict log entries since log_id, inclusive.

async fn purge_logs_upto( &mut self, log_id: LogId<MemNodeId> ) -> Result<(), StorageError<MemNodeId>>
