Struct ValueI

pub struct ValueI(pub usize);

A ValueI represents an index into Slab.ps.vals.

It behaves much like a pointer or reference, but it is ‘safe’ (unlike a raw pointer) and is not managed by the Rust borrow checker (unlike a reference).

Tuple Fields

0: usize

Implementations

impl ValueI

pub fn from(self, ps: &ParseSlab) -> &Value

Gets a Value reference from the ParseSlab.

See the comments on ExpressionI::from.

Trait Implementations

impl Clone for ValueI

fn clone(&self) -> ValueI

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ValueI

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

Formats the value using the given formatter.

impl PartialEq for ValueI

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