Macro nom_locate::impl_input_iter

macro_rules! impl_input_iter {
    ($fragment_type : ty, $item : ty, $raw_item : ty, $iter : ty, $iter_elem : ty) => { ... };
}

Implement nom::InputIter for a specific fragment type

Parameters

• $fragment_type - The LocatedSpan’s fragment type
• $item - The type of the item being iterated (a reference for fragments of type &[T]).
• $raw_item - The raw type of the item being iterating (dereferenced type of $item for &[T], otherwise same as $item)
• $iter - The iterator type for iter_indices()
• $iter_elem - The iterator type for iter_elements()

Example of use

NB: This example is an extract from the nom_locate source code.

#[macro_use]
extern crate nom_locate;

impl_input_iter!(&'a str, char, char, CharIndices<'a>, Chars<'a>);
impl_input_iter!(&'a [u8], &'a u8, u8, Enumerate<Iter<'a, Self::RawItem>>,
                 Iter<'a, Self::RawItem>);
