The unary Math functions the Opcode::MathUnary fast path recognizes (#186). f64→f64; the discriminant is the opcode operand. Kept in sync with the VM handler and the JIT lowering.

Implementations

impl MathUnaryFn

pub fn from_name(name: &str) -> Option<MathUnaryFn>

Map a Math.<name> member to its id, or None if it isn’t a supported unary intrinsic.

pub fn from_u16(v: u16) -> Option<MathUnaryFn>

Decode an opcode operand to the fn id (safe match — no transmute).

pub fn apply(self, x: f64) -> f64

Apply the intrinsic (the single source of truth for VM + JIT + interp result parity).

Trait Implementations

impl Clone for MathUnaryFn

fn clone(&self) -> MathUnaryFn

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for MathUnaryFn

impl Debug for MathUnaryFn

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

Formats the value using the given formatter.

impl Eq for MathUnaryFn

impl PartialEq for MathUnaryFn

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