Struct Stdin

pub struct Stdin;

Only public interface is the HostInputStream impl.

Trait Implementations

impl Clone for Stdin

fn clone(&self) -> Stdin

Returns a copy of the value.

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

Performs copy-assignment from source.

impl HostInputStream for Stdin

fn read(&mut self, size: usize) -> Result<Bytes, StreamError>

Reads up to size bytes, returning a buffer holding these bytes on success.

fn blocking_read<'life0, 'async_trait>( &'life0 mut self, size: usize, ) -> Pin<Box<dyn Future<Output = StreamResult<Bytes>> + Send + 'async_trait>>

where Self: Send + 'async_trait, 'life0: 'async_trait,

Similar to read, except that it blocks until at least one byte can be read.

fn skip(&mut self, nelem: usize) -> StreamResult<usize>

Same as the read method except that bytes are skipped.

fn blocking_skip<'life0, 'async_trait>( &'life0 mut self, nelem: usize, ) -> Pin<Box<dyn Future<Output = StreamResult<usize>> + Send + 'async_trait>>

where Self: Send + 'async_trait, 'life0: 'async_trait,

Similar to skip, except that it blocks until at least one byte can be skipped.

fn cancel<'life0, 'async_trait>( &'life0 mut self, ) -> Pin<Box<dyn Future<Output = ()> + Send + 'async_trait>>

where Self: Send + 'async_trait, 'life0: 'async_trait,

Cancel any asynchronous work and wait for it to wrap up.

impl StdinStream for Stdin

fn stream(&self) -> Box<dyn HostInputStream>

Creates a fresh stream which is reading stdin.

fn isatty(&self) -> bool

Returns whether this stream is backed by a TTY.

impl Subscribe for Stdin

fn ready<'life0, 'async_trait>( &'life0 mut self, ) -> Pin<Box<dyn Future<Output = ()> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

An asynchronous function which resolves when this object’s readiness operation is ready.
