Trait Implementations§

Source§

impl<'de> SeqAccess<'de> for ListGetter<'de>

Source§

type Error = Error

Source§

fn next_element_seed<T>(&mut self, seed: T) -> Result<Option<T::Value>>
where T: DeserializeSeed<'de>,

This returns Ok(Some(value)) for the next value in the sequence, or Ok(None) if there are no more remaining items. Read more
Source§

Source§

fn size_hint(&self) -> Option<usize>

Returns the number of elements remaining in the sequence, if known.
