Struct ExprId 

pub struct ExprId(/* private fields */);

Handle into the expression graph. Lightweight (4 bytes), Copy.

Implementations

impl ExprId

Well-known node indices, pre-populated in every graph.

pub const ZERO: Self

The constant 0.0 (index 0).

pub const ONE: Self

The constant 1.0 (index 1).

pub const TWO: Self

The constant 2.0 (index 2).

pub fn from_index(index: u32) -> Self

Create an ExprId from a raw index.

pub fn index(&self) -> u32

The raw index of this expression in the graph.

impl ExprId

pub fn var(n: u16) -> Self

Create a variable node in the thread-local graph.
