Struct deno_core::CancelHandle

pub struct CancelHandle { /* private fields */ }

Implementations

impl CancelHandle

pub fn new() -> Self

pub fn new_rc() -> Rc<Self>

pub fn cancel(&self)

Cancel all cancelable futures that are bound to this handle. Note that this method does not require a mutable reference to the CancelHandle.

pub fn is_canceled(&self) -> bool

Trait Implementations

impl Debug for CancelHandle

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for CancelHandle

fn default() -> CancelHandle

Returns the “default value” for a type.

impl Resource for CancelHandle

fn name(&self) -> Cow<'_, str>

Returns a string representation of the resource which is made available to JavaScript code through op_resources. The default implementation returns the Rust type name, but specific resource types may override this trait method.

fn close(self: Rc<Self>)

Resources may implement the close() trait method if they need to do resource specific clean-ups, such as cancelling pending futures, after a resource has been removed from the resource table.

fn read_return(
    self: Rc<Self>,
    _buf: ZeroCopyBuf
) -> AsyncResult<(usize, ZeroCopyBuf)>

Resources may implement read_return() to be a readable stream

fn write(self: Rc<Self>, _buf: ZeroCopyBuf) -> AsyncResult<usize>

Resources may implement write() to be a writable stream

fn shutdown(self: Rc<Self>) -> AsyncResult<()>

Resources may implement shutdown() for graceful async shutdowns

fn backing_fd(self: Rc<Self>) -> Option<RawFd>

Resources backed by a file descriptor can let ops know to allow for low-level optimizations.

fn size_hint(&self) -> (u64, Option<u64>)
