Module vec2 

2-D vector helpers.

Vec2 is a type alias over [f64; 2] so it is ABI-compatible with any [f64; 2] used elsewhere in the workspace.

Functions

add

a + b.

cross

2-D cross product (scalar, = a × b z-component).

distance

Euclidean distance |a - b|.

dot

a · b.

lerp

Linear interpolation a + t * (b - a).

norm

|a|.

norm_squared

|a|².

normalize

Unit vector or [0, 0] if |a| is below machine epsilon.

rotate

Rotate v by angle radians (counter-clockwise).

scale

a * s.

sub

a - b.

Type Aliases
