Expand description

A list accessor

Implementations§

source§

impl<'a> ListAccessor<'a>

source

pub fn len(&self) -> usize

Returns the number of elements in the list

source

pub fn is_empty(&self) -> bool

Returns true if the list has a length of 0

source

pub fn iter(&'a self) -> impl Iterator<Item = ValueAccessor<'a>> + 'a

Returns an iterator over the list

source

pub fn get(&self, idx: usize) -> Option<ValueAccessor<'a>>

Returns a reference to an element depending on the index

source

pub fn try_get(&self, idx: usize) -> Result<ValueAccessor<'a>, Error>

Like ListAccessor::get, returns Err if the index does not exist
