Struct deno_core::CancelHandle

source ·
pub struct CancelHandle { /* private fields */ }

Implementations§

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

Trait Implementations§

Formats the value using the given formatter. Read more
Returns the “default value” for a type. Read more
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.
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 a single chunk of data from the resource. This operation returns a BufView that represents the data that was read. If a zero length buffer is returned, it indicates that the resource has reached EOF. Read more
Read a single chunk of data from the resource into the provided BufMutView. Read more
Write a single chunk of data to the resource. The operation may not be able to write the entire chunk, in which case it should return the number of bytes written. Additionally it should return the BufView that was passed in. Read more
Write an entire chunk of data to the resource. Unlike write(), this will ensure the entire chunk is written. If the operation is not able to write the entire chunk, an error is to be returned. Read more
The shutdown method can be used to asynchronously close the resource. It is not automatically called when the resource is dropped or closed. Read more
Resources backed by a file descriptor can let ops know to allow for low-level optimizations.
