Struct WorkflowRandomStream 

pub struct WorkflowRandomStream { /* private fields */ }

A pseudo-random stream private to a stable caller-supplied name.

Obtain a stream with WorkflowContext::random_stream, SyncWorkflowContext::random_stream, or crate::workflow_interceptors::WorkflowInterceptorContext::random_stream. Looking up the same name again continues the same stream, while different names and the context’s default WorkflowContext::random stream do not consume one another. Clones of this value refer to the same named stream.

Draws advance workflow state without recording individual values in history, so replaying code must draw from a given name in the same order. Adding or removing draws from one name does not change any other name.

Workflow reset replays the original sequence through the reset point. When Core supplies the reset run’s new randomness seed, all named streams start new sequences for work after that point. Continue-as-new creates a new workflow run and independently seeds all streams.

Implementations

impl WorkflowRandomStream

pub fn random<T>(&self) -> T

where T: WorkflowRandomValue,

Generates the next pseudo-random value from this named stream.

This generator is not cryptographically secure.

pub fn name(&self) -> &str

Returns the stable name associated with this stream.

Trait Implementations

impl Clone for WorkflowRandomStream

fn clone(&self) -> WorkflowRandomStream

Returns a duplicate of the value.

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

Performs copy-assignment from source.
