Enum HostDirection 

pub enum HostDirection {
    Input,
    Output,
    Duplex,
}

Direction of a host stream relative to the device.

Variants

Input

Device delivers data into the runtime (a source).

Output

Device receives data from the runtime (a sink).

Duplex

Device both delivers and receives data.

Implementations

impl HostDirection

pub fn stream_direction(self) -> StreamDirection

Maps this host direction to the core StreamDirection.

pub fn symbol(self) -> Symbol

Returns the stable qualified symbol naming this direction.

pub fn effect_kind(self) -> Symbol

Returns the effect kind an open in this direction performs (device read for input, device write for output or duplex).

Trait Implementations

impl Clone for HostDirection

fn clone(&self) -> HostDirection

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for HostDirection

impl Debug for HostDirection

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

Formats the value using the given formatter.

impl Eq for HostDirection

impl PartialEq for HostDirection

fn eq(&self, other: &HostDirection) -> 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.
