Struct HarrenIter 

pub struct HarrenIter { /* private fields */ }

An Iterator-like structure for taking ownership of the elements of a HarrenVec.

(Note that if the no_drop feature is enabled, then this iterator will not call the destructors of any of its contents when dropped. Instead you should use the next method to ensure you are consuming and dropping each value.

If the contents do not have a Drop implementation, this is not a concern.)

Implementations

impl HarrenIter

pub fn peek_type(&self) -> Option<TypeId>

Checks the type of the next item in the iterator without actually advancing it.

Examples

use std::any::TypeId;
use hvec::hvec;

let list = hvec![1_u64, 2_i32];
let mut iter = list.into_iter();
assert_eq!(iter.peek_type(), Some(TypeId::of::<u64>()));

pub fn next<T: 'static>(&mut self) -> Option<T>

Advances the iterator and returns the next item if one exists - or else None.

Panics

(This method can only panic if the type_assertions feature flag is enabled.)

This method will panic if the actual type of the item differs from the T that this method was called with.

Examples

use hvec::hvec;

let list = hvec![1_u64, 2_i32];
let mut iter = list.into_iter();
assert_eq!(iter.next::<u64>(), Some(1_u64));
assert_eq!(iter.next::<i32>(), Some(2_i32));
assert_eq!(iter.next::<()>(), None);

pub unsafe fn next_unchecked<T: 'static>(&mut self) -> Option<T>

See Self::next. Does not panic if the type doesn’t match.

Safety

This method is only safe if the bytes can be safely interpreted as a struct of type T.

pub fn is_empty(&self) -> bool

Returns true if there are no more elements in the iterator.
