Struct IterVTable

#[non_exhaustive]
#[repr(C)]
pub struct IterVTable<T: IterItem> {
    pub init_with_value: Option<IterInitWithValueFn>,
    pub next: IterNextFn<T>,

VTable for an iterator

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.

init_with_value: Option<IterInitWithValueFn>

cf. IterInitWithValueFn

next: IterNextFn<T>

cf. IterNextFn

next_back: Option<IterNextBackFn<T>>

cf. IterNextBackFn

size_hint: Option<IterSizeHintFn>

cf. IterSizeHintFn

dealloc: IterDeallocFn

cf. IterDeallocFn

Implementations

impl<T: IterItem> IterVTable<T>

pub const fn builder() -> IterVTableBuilder<T>

Returns a builder for IterVTable

Trait Implementations

impl<T: Clone + IterItem> Clone for IterVTable<T>

fn clone(&self) -> IterVTable<T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Debug + IterItem> Debug for IterVTable<T>

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

Formats the value using the given formatter.

impl<T: Hash + IterItem> Hash for IterVTable<T>

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

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<T: PartialEq + IterItem> PartialEq for IterVTable<T>

fn eq(&self, other: &IterVTable<T>) -> 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.
