Struct List

pub struct List { /* private fields */ }

List represents a list which contains an array of elements.

Implementations

impl List

pub fn len(&self) -> usize

Get the number of fields in this row

pub fn elements(&self) -> &[Field]

Get the reference to the elements in this list

Trait Implementations

impl PartialEq for List

fn eq(&self, other: &List) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
