Struct MapIterVTable

#[non_exhaustive]
#[repr(C)]
pub struct MapIterVTable {
    pub next: for<'iter> unsafe fn(PtrMut<'iter>) -> Option<(PtrConst<'iter>, PtrConst<'iter>)>,
    pub dealloc: for<'iter> unsafe fn(PtrMut<'iter>),
}

VTable for an iterator over a map

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

next: for<'iter> unsafe fn(PtrMut<'iter>) -> Option<(PtrConst<'iter>, PtrConst<'iter>)>

cf. MapIterNextFn

dealloc: for<'iter> unsafe fn(PtrMut<'iter>)

cf. MapIterDeallocFn

Implementations

impl MapIterVTable

pub const fn builder() -> MapIterVTableBuilder

Returns a builder for MapIterVTable

Trait Implementations

impl Clone for MapIterVTable

fn clone(&self) -> MapIterVTable

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for MapIterVTable

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

Formats the value using the given formatter.

impl Hash for MapIterVTable

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for MapIterVTable

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