Struct Iter

Source
pub struct Iter<'a, C, S>
where C: Config,
{ /* private fields */ }
Expand description

An iterator-like structure for the raw trie.

This wraps the map and provides borrowed instances of the payloads. Note that due to the borrowing from the iterator itself, it is not possible to create the true Iterator. As this is used to implement the iterators of the wrapper convenience types, this is not considered a serious limitation.

§Quirks

As noted in the crate-level documentation, changes to the content of the map done during the lifetime of the iterator (both in the current thread and other threads) may or may not be reflected in the returned values.

Implementations§

Source§

impl<'a, C, S> Iter<'a, C, S>
where C: Config,

Source

pub fn new<'m: 'a>(map: &'m Raw<C, S>) -> Self

Creates a new iterator, borrowing from the map.

Source

pub fn next(&mut self) -> Option<&C::Payload>

Produces another value, just like Iterator::next, except the value is bound to the lifetime of the iterator structure.
