Struct fdf::DispatcherBuilder

pub struct DispatcherBuilder { /* private fields */ }

A builder for Dispatchers

Implementations

impl DispatcherBuilder

pub fn new() -> Self

Creates a new DispatcherBuilder that can be used to configure a new dispatcher. For more information on the threading-related flags for the dispatcher, see https://fuchsia.dev/fuchsia-src/concepts/drivers/driver-dispatcher-and-threads

pub fn unsynchronized(self) -> Self

Sets whether parallel callbacks in the callbacks set in the dispatcher are allowed. May not be set with Self::allow_thread_blocking.

See https://fuchsia.dev/fuchsia-src/concepts/drivers/driver-dispatcher-and-threads for more information on the threading model of driver dispatchers.

pub fn is_unsynchronized(&self) -> bool

Whether or not this is an unsynchronized dispatcher

pub fn allow_thread_blocking(self) -> Self

This dispatcher may not share zircon threads with other drivers. May not be set with Self::unsynchronized.

See https://fuchsia.dev/fuchsia-src/concepts/drivers/driver-dispatcher-and-threads for more information on the threading model of driver dispatchers.

pub fn allows_thread_blocking(&self) -> bool

pub fn name(self, name: &str) -> Self

A descriptive name for this dispatcher that is used in debug output and process lists.

pub fn scheduler_role(self, role: &str) -> Self

A hint string for the runtime that may or may not impact the priority the work scheduled by this dispatcher is handled at. It may or may not impact the ability for other drivers to share zircon threads with the dispatcher.

pub fn shutdown_observer<F: ShutdownObserverFn>( self, shutdown_observer: F, ) -> Self

A callback to be called before after the dispatcher has completed asynchronous shutdown.

pub fn create(self) -> Result<Dispatcher, Status>

Create the dispatcher as configured by this object. This must be called from a thread managed by the driver runtime. The dispatcher returned is owned by the caller, and will initiate asynchronous shutdown when the object is dropped unless Dispatcher::release is called on it to convert it into an unowned DispatcherRef.

pub fn create_released(self) -> Result<DispatcherRef<'static>, Status>

As with Self::create, this creates a new dispatcher as configured by this object, but instead of returning an owned reference it immediately releases the reference to be managed by the driver runtime.

Trait Implementations

impl Default for DispatcherBuilder

fn default() -> DispatcherBuilder

Returns the “default value” for a type.
