Struct CommandBatch 

pub struct CommandBatch<C> {
    pub batch_id: BatchId,
    pub scope: AtomicityScope,
    pub envelopes: Vec<CommandEnvelope<C>>,
}

A group of envelopes executed under one atomicity scope.

Fields

batch_id: BatchId

Identifier of the batch.

scope: AtomicityScope

Scope under which the envelopes commit.

envelopes: Vec<CommandEnvelope<C>>

The envelopes, in execution order.

Implementations

impl<C> CommandBatch<C>

pub fn len(&self) -> usize

Number of envelopes.

pub fn is_empty(&self) -> bool

Returns true when the batch has no envelopes.

pub fn is_single_case(&self) -> bool

Returns true when every envelope targets the same case (required for AtomicityScope::PerCase).

pub fn try_map<D, E>( self, f: impl FnMut(C) -> Result<D, E>, ) -> Result<CommandBatch<D>, E>

Transforms every command payload, keeping identifiers and scope.
