Required Associated Types

type Output: Send + Sync

Trait Implementations

impl<O: Send + Sync> Debug for dyn Function<Output = O>

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

Formats the value using the given formatter.

impl<O: Send + Sync> Display for dyn Function<Output = O>

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

Formats the value using the given formatter.

impl<O: Send + Sync> PartialEq for dyn Function<Output = O>

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