Implementations

impl StreamDirection

pub fn symbol(self) -> Symbol

Returns the stream/direction/* symbol identifying this direction.

pub fn from_symbol(symbol: &Symbol) -> Result<Self>

Parses a StreamDirection from its stream/direction/* symbol.

Returns an error for any symbol outside the known directions.

Trait Implementations

impl Clone for StreamDirection

fn clone(&self) -> StreamDirection

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for StreamDirection

impl Debug for StreamDirection

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

Formats the value using the given formatter.

impl Eq for StreamDirection

impl PartialEq for StreamDirection

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