Struct Handler

Source

pub struct Handler<H: EffectHandler> { /* private fields */ }

Expand description

A handler and the capabilities it is registered with. Pass it to RuntimeBuilder::register.

Implementations§

Source §

impl<H: EffectHandler> Handler<H>

Source

pub fn new(handler: H) -> Self

Registers handler with no optional capabilities.

Source §

impl<H: CompensableEffect> Handler<H>

Source

pub fn compensable(self) -> Self

Lets the effect be undone with Runtime::compensate, using CompensableEffect::compensate, and lets recovery finish an interrupted compensation.

Source §

impl<H: VerifiableEffect> Handler<H>

Source

pub fn verifiable(self) -> Self

Verifies the effect after every success and to resolve unknown outcomes, using VerifiableEffect::verify.
