Implementations

impl OperatorState

pub const fn is_open(self) -> bool

pub const fn is_finished(self) -> bool

Returns true if the operator has finished.

pub const fn is_closed(self) -> bool

Returns true if the operator is closed.

Trait Implementations

impl Clone for OperatorState

fn clone(&self) -> OperatorState

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OperatorState

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

Formats the value using the given formatter.

impl PartialEq for OperatorState

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