Struct glsp::GIter

pub struct GIter { /* fields omitted */ }

The iter primitive type.

The name GIter was chosen to avoid confusion with Rust's iterators.

It's possible to use a Root<GIter> as a Rust iterator. However, collection types like Arr also provide methods to create native Rust iterators, which will generally have much better performance.

Implementations

impl GIter

pub fn shallow_clone(&self) -> Root<GIter>

Creates a shallow copy of the iterator.

Equivalent to (clone it).

pub fn is_finished(&self) -> bool

Returns true if the iterator has finished.

Equivalent to (iter-finished? it).

pub fn len(&self) -> GIterLen

Returns the iterator's remaining length.

Equivalent to (len it).

pub fn is_double_ended(&self) -> bool

Returns true if the iterator is double-ended.

Equivalent to (iter-double-ended? it).

pub fn next(&self) -> Option<Result<Val, GError>>

Advances the iterator and returns its next item.

Equivalent to (iter-next! it).

pub fn next_back(&self) -> Option<Result<Val, GError>>

Advances the iterator from the back and returns its next item.

Equivalent to (iter-next-back! it).
