Struct PortId 

pub struct PortId(pub usize);

Identifies an I/O port.

Standard ports (STDIN, STDOUT, STDERR) are pre-defined. Implementations may allocate additional ports for file or string I/O.

Tuple Fields

0: usize

Implementations

impl PortId

pub const STDIN: PortId

Standard input port.

pub const STDOUT: PortId

Standard output port.

pub const STDERR: PortId

Standard error port.

Trait Implementations

impl Clone for PortId

fn clone(&self) -> PortId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PortId

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

Formats the value using the given formatter.

impl PartialEq for PortId

fn eq(&self, other: &PortId) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
