Trait Implementations
sourceimpl Default for StdFileResource
impl Default for StdFileResource
sourcefn default() -> StdFileResource
fn default() -> StdFileResource
Returns the “default value” for a type. Read more
sourceimpl Resource for StdFileResource
impl Resource for StdFileResource
sourcefn name(&self) -> Cow<'_, str>
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. Read more
fn read_return(
self: Rc<Self>,
buf: ZeroCopyBuf
) -> AsyncResult<(usize, ZeroCopyBuf)>
sourcefn write(self: Rc<Self>, buf: ZeroCopyBuf) -> AsyncResult<usize>
fn write(self: Rc<Self>, buf: ZeroCopyBuf) -> AsyncResult<usize>
Resources may implement write()
to be a writable stream
sourcefn close(self: Rc<Self>)
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. Read more
