Struct Punctuated

pub struct Punctuated<T: Parse, P: Parse> {
    pub first: Box<T>,
    pub collection: Vec<(P, T)>,
}

A utility struct for collections of parsed items with punctuators between them.

Fields

first: Box<T>

The first parsed item.

collection: Vec<(P, T)>

The next items with punctuators.

Implementations

impl<T: Parse, P: Parse> Punctuated<T, P>

pub fn new(first: T) -> Punctuated<T, P>

Creates a new instance of Punctuated.

pub fn iter(&self) -> impl Iterator<Item = &T>

Turns the punctuated into an iterator on the items.

pub fn into_parsed_iter(self) -> impl Iterator<Item = T>

Turns the punctuated into an iterator on the items.

pub fn len(&self) -> usize

Gets the item count.

pub fn is_empty(&self) -> bool

Checks if there are no items (always false).

pub fn get(&self, index: usize) -> Option<&T>

Tries to get the element on index.
