Struct DispatchImpactAccumulator 

pub struct DispatchImpactAccumulator { /* private fields */ }

Lossless request-scoped accumulator for installed subcommit effects.

Implementations

impl DispatchImpactAccumulator

pub const fn new() -> Self

Starts an empty request accumulator.

pub fn record( &mut self, effect: DispatchEffect, targets: impl IntoIterator<Item = DispatchTarget>, )

Records one truthful effect after its durable subcommit is installed.

Repeated effects union exact target sets. An empty target iterator still records the effect because lack of a current binding does not erase a committed permission change.

pub fn merge(&mut self, prefix: Self)

Merges another installed-prefix accumulator without replacing any earlier effect or target.

pub fn is_empty(&self) -> bool

Returns whether no committed subcommit recorded an effect.

pub fn finish(self, conversation_id: ConversationId) -> DispatchImpact

Converts the request accumulator into its externally carried impact.

Trait Implementations

impl Debug for DispatchImpactAccumulator

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

impl Default for DispatchImpactAccumulator

fn default() -> DispatchImpactAccumulator

Returns the “default value” for a type.
