ArrayIterator

Struct ArrayIterator 

Source
pub struct ArrayIterator<'bytes, 'parent, B, S>
where B: BytesLike<'bytes>, S: Stack,
{ /* private fields */ }
Expand description

An iterator over an array.

Implementations§

Source§

impl<'bytes, 'parent, B, S> ArrayIterator<'bytes, 'parent, B, S>
where B: BytesLike<'bytes>, S: Stack,

Source

pub fn next( &mut self, ) -> Option<Result<Value<'bytes, '_, B, S>, JsonError<'bytes, B, S>>>

The next item within the array.

This is approximate to Iterator::next yet each item maintains a mutable reference to the iterator. Accordingly, we cannot use Iterator::next which requires items not borrow from the iterator.

polonius-the-crab details a frequent limitation of Rust’s borrow checker which users of this function may incur. It also details potential solutions (primarily using inlined code instead of functions, callbacks) before presenting itself as a complete solution. Please refer to it if you have difficulties calling this method for context.
