Struct zng :: hot_reload :: HOT_RELOAD Copy item path

impl HOT_RELOAD

pub fn status(&self) -> ReadOnlyVar<Vec<HotStatus>, ArcVar<Vec<HotStatus>>>

Hot reload status, libs that are rebuilding, errors.

pub fn rebuilder( &self, rebuilder: impl FnMut(BuildArgs) -> Option<ReadOnlyVar<Response<Result<PathBuf, BuildError>>, ArcVar<Response<Result<PathBuf, BuildError>>>>> + Send + 'static, )

Register a handler that can override the hot library rebuild.

The command should rebuild using the same features used to run the program (not just rebuild the dylib). By default it is just cargo build, that works if the program was started using only cargo run, but an example program needs a custom runner.

If rebuilder wants to handle the rebuild it must return a response var that updates when the rebuild is finished with the path to the rebuilt dylib. The BuildArgs also provides helper methods to rebuild common workspace setups.

Note that unlike most services the rebuilder is registered immediately, not after an update cycle.

pub fn rebuild(&self, manifest_dir: impl Into<Txt>)

Request a rebuild, if manifest_dir is a hot library.

Note that changes inside the directory already trigger a rebuild automatically.

pub fn cancel(&self, manifest_dir: impl Into<Txt>)

Request a rebuild cancel for the current building manifest_dir.

impl UnwindSafe for HOT_RELOAD

Blanket Implementations§

impl<T> Any for T
where T: 'static + ?Sized,

fn type_id(&self) -> TypeId

Gets the TypeId of self. Read more

impl<T> Borrow<T> for T
where T: ?Sized,

fn borrow(&self) -> &T

Immutably borrows from an owned value. Read more

impl<T> BorrowMut<T> for T
where T: ?Sized,

fn borrow_mut(&mut self) -> &mut T

Mutably borrows from an owned value. Read more

impl<T> Downcast for T
where T: Any,

fn into_any(self: Box<T>) -> Box<dyn Any>

Convert Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can then be further downcast into Box<ConcreteType> where ConcreteType implements Trait.

fn into_any_rc(self: Rc<T>) -> Rc<dyn Any>

Convert Rc<Trait> (where Trait: Downcast) to Rc<Any>. Rc<Any> can then be further downcast into Rc<ConcreteType> where ConcreteType implements Trait.

fn as_any(&self) -> &(dyn Any + 'static)

Convert &Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &Any’s vtable from &Trait’s.

fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)

Convert &mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &mut Any’s vtable from &mut Trait’s.

impl<T> DowncastSync for T
where T: Any + Send + Sync,

fn into_any_arc(self: Arc<T>) -> Arc<dyn Any + Sync + Send>

Convert Arc<Trait> (where Trait: Downcast) to Arc<Any>. Arc<Any> can then be further downcast into Arc<ConcreteType> where ConcreteType implements Trait.

impl<T> From<T> for T

fn from(t: T) -> T

Returns the argument unchanged.

impl<T> Instrument for T

fn instrument(self, span: Span) -> Instrumented<Self>

Instruments this type with the provided [Span], returning an Instrumented wrapper. Read more

fn in_current_span(self) -> Instrumented<Self>

Instruments this type with the current Span, returning an Instrumented wrapper. Read more

impl<T> Instrument for T

fn instrument(self, span: Span) -> Instrumented<Self>

Instruments this type with the provided Span, returning an Instrumented wrapper. Read more

fn in_current_span(self) -> Instrumented<Self>

impl<T, U> Into for T
where U: From<T>,

fn into(self) -> U

impl<T> IntoEither for T

fn into_either(self, into_left: bool) -> Either<Self, Self>

Converts self into a Left variant of Either<Self, Self> if into_left is true. Converts self into a Right variant of Either<Self, Self> otherwise. Read more

fn into_either_with<F>(self, into_left: F) -> Either<Self, Self>
where F: FnOnce(&Self) -> bool,

Converts self into a Left variant of Either<Self, Self> if into_left(&self) returns true. Converts self into a Right variant of Either<Self, Self> otherwise. Read more
