Variants

ImplFn

impl FnX(i32, i32) -> i32, where FnX is the most special trait between Fn, FnMut, FnOnce that the closure implements. This is the default.

RANotation

|i32, i32| -> i32

ClosureWithId

{closure#14825}, useful for some diagnostics (like type mismatch) and internal usage.

ClosureWithSubst

{closure#14825}<i32, ()>, useful for internal usage.

Hide

…, which is the TYPE_HINT_TRUNCATION

Trait Implementations

impl Clone for ClosureStyle

fn clone(&self) -> ClosureStyle

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ClosureStyle

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

Formats the value using the given formatter.

impl PartialEq for ClosureStyle

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