Trait Implementations§

source§

impl Debug for Func

source§

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

Formats the value using the given formatter. Read more
source§

impl From<Func> for Robj

source§

fn from(val: Func) -> Self

Converts to this type from the input type.
source§

impl PartialEq for Func

source§

fn eq(&self, other: &Func) -> bool

Tests for self and other values to be equal, and is used by ==.
1.0.0 · source§

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
