Struct deno_cli::resources::Resource

pub struct Resource {
    pub rid: ResourceId,
}

Fields

rid: ResourceId

Methods

impl Resource

pub fn poll_accept(&mut self) -> Poll<(TcpStream, SocketAddr), Error>

pub fn poll_accept_tls(
    &mut self,
    tcp_stream: TcpStream
) -> impl Future<Item = ServerTlsStream<TcpStream>, Error = Error>

pub fn track_task(&mut self) -> Result<(), Error>

Track the current task (for TcpListener resource). Throws an error if another task is already tracked.

pub fn untrack_task(&mut self)

Stop tracking a task (for TcpListener resource). Happens when the task is done and thus no further tracking is needed.

pub fn close(&self)

pub fn shutdown(&mut self, how: Shutdown) -> Result<(), ErrBox>

Trait Implementations

impl DenoAsyncRead for Resource

fn poll_read(&mut self, buf: &mut [u8]) -> Poll<usize, ErrBox>

impl DenoAsyncWrite for Resource

fn poll_write(&mut self, buf: &[u8]) -> Poll<usize, ErrBox>

fn shutdown(&mut self) -> Poll<(), ErrBox>

impl Clone for Resource

Important traits for Resource

impl Read for Resourceimpl Write for Resource

fn clone(&self) -> Resource

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Resource

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

Formats the value using the given formatter.

impl Read for Resource

fn read(&mut self, _buf: &mut [u8]) -> Result<usize>

Pull some bytes from this source into the specified buffer, returning how many bytes were read.

fn read_vectored(&mut self, bufs: &mut [IoSliceMut]) -> Result<usize, Error>

Like read, except that it reads into a slice of buffers.

unsafe fn initializer(&self) -> Initializer

🔬 This is a nightly-only experimental API. (read_initializer)

Determines if this Reader can work with buffers of uninitialized memory.

fn read_to_end(&mut self, buf: &mut Vec<u8>) -> Result<usize, Error>

Read all bytes until EOF in this source, placing them into buf.

fn read_to_string(&mut self, buf: &mut String) -> Result<usize, Error>

Read all bytes until EOF in this source, appending them to buf.

fn read_exact(&mut self, buf: &mut [u8]) -> Result<(), Error>

Read the exact number of bytes required to fill buf.

fn by_ref(&mut self) -> &mut Self

Creates a "by reference" adaptor for this instance of Read.

fn bytes(self) -> Bytes<Self>

Transforms this Read instance to an [Iterator] over its bytes.

fn chain<R>(self, next: R) -> Chain<Self, R> where
    R: Read, 

Creates an adaptor which will chain this stream with another.

fn take(self, limit: u64) -> Take<Self>

Creates an adaptor which will read at most limit bytes from it.

impl Write for Resource

fn write(&mut self, _buf: &[u8]) -> Result<usize>

Write a buffer into this writer, returning how many bytes were written.

fn flush(&mut self) -> Result<()>

Flush this output stream, ensuring that all intermediately buffered contents reach their destination.

fn write_vectored(&mut self, bufs: &[IoSlice]) -> Result<usize, Error>

Like write, except that it writes from a slice of buffers.

fn write_all(&mut self, buf: &[u8]) -> Result<(), Error>

Attempts to write an entire buffer into this writer.

fn write_fmt(&mut self, fmt: Arguments) -> Result<(), Error>

Writes a formatted string into this writer, returning any error encountered.

fn by_ref(&mut self) -> &mut Self

Creates a "by reference" adaptor for this instance of Write.
