Enum MergeStrategy 

pub enum MergeStrategy {
    Exclusive,
    Commutative,
}

Parallel merge strategy for a state key.

Determines how concurrent updates to the same key are handled when merging MutationBatches from parallel tool execution.

Variants

Exclusive

Concurrent updates to this key are mutually exclusive. Parallel batches that both touch this key cannot be merged.

Commutative

Updates to this key are commutative — they can be applied in any order and produce the same result. Parallel batches that both touch this key will have their ops concatenated.

Trait Implementations

impl Clone for MergeStrategy

fn clone(&self) -> MergeStrategy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MergeStrategy

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

Formats the value using the given formatter.

impl Default for MergeStrategy

fn default() -> MergeStrategy

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for MergeStrategy

fn deserialize<__D>( __deserializer: __D, ) -> Result<MergeStrategy, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for MergeStrategy

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

impl Serialize for MergeStrategy

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for MergeStrategy
