Enum ArrayIndexKind 

pub enum ArrayIndexKind {
    Push,
    Current,
    Specific(usize),
}

Kind of array index used in a path segment.

Variants

Push

[] — always pushes a new element onto the array

Current

[^] — references the element most recently pushed into this array within the current block scope. Errors if there is no such push in scope.

Specific(usize)

[n] — references a specific index, creating the element if it does not exist

Trait Implementations

impl Clone for ArrayIndexKind

fn clone(&self) -> ArrayIndexKind

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ArrayIndexKind

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Hash for ArrayIndexKind

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for ArrayIndexKind

fn eq(&self, other: &ArrayIndexKind) -> 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.
