Trait Implementations

impl Clone for LBool

fn clone(&self) -> LBool

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LBool

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

Formats the value using the given formatter.

impl From<bool> for LBool

fn from(b: bool) -> Self

Converts to this type from the input type.

impl PartialEq for LBool

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

impl Copy for LBool

impl Eq for LBool
