Enum WarnState 

pub enum WarnState {
    Off,
    On,
}

PUC 5.4+ default warnf state. The base library’s warn function flips between Off and On via the @on / @off control messages; any other @<word> control is silently ignored, mirroring lauxlib.c::checkcontrol.

Variants

Off

warn calls are silently dropped (default after warn("@off")).

On

warn calls are delivered to stderr (after warn("@on")).

Trait Implementations

impl Clone for WarnState

fn clone(&self) -> WarnState

Returns a duplicate of the value.

Performs copy-assignment from source.

impl Copy for WarnState

impl Debug for WarnState

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

impl Eq for WarnState

impl PartialEq for WarnState

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