Trait steno::SagaType

pub trait SagaType: Debug + 'static {
    type ExecContextType: Debug + Send + Sync + 'static;
}

Collection of consumer-provided types, effectively defining the type signature of a saga

This trait bundles a bunch of consumer-provided types that are used throughout Steno to avoid a sprawl of type parameters and duplicated trait bounds.

type ExecContextType: Debug + Send + Sync + 'static

Type for the consumer’s context object

When beginning execution of a saga with crate::SecClient::saga_create() or resuming a previous execution with crate::SecClient::saga_resume(), consumers provide a context object with this type. This object is not persistent. Rather, it provides programming interfaces the consumer wants available from within actions. For example, this could include HTTP clients that will be used by the action to make requests to dependent services. This object is made available to actions via crate::ActionContext::user_data(). There’s one context for the life of each saga’s execution.
