Enum Choice 

#[repr(u8)]
pub enum Choice {
    Unknown = 0,
    Left = 1,
    Right = 2,
    Both = 3,
}

A single choice made at a min/max node.

Explicitly stored in a u8 so that this can be written by JIT functions, which have no notion of Rust enums.

Note that this is a bitfield such that

Choice::Both as u8 == Choice::Left as u8 | Choice::Right as u8

Variants

Unknown = 0

This choice has not yet been assigned

A value of Unknown is invalid after evaluation

Left = 1

The operation always picks the left-hand input

Right = 2

The operation always picks the right-hand input

Both = 3

The operation may pick either input

Trait Implementations

impl BitAndAssign for Choice

fn bitand_assign(&mut self, other: Self)

Performs the &= operation.

impl BitOrAssign for Choice

fn bitor_assign(&mut self, other: Self)

Performs the |= operation.

impl Clone for Choice

fn clone(&self) -> Choice

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Choice

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

Formats the value using the given formatter.

impl Not for Choice

type Output = Choice

The resulting type after applying the ! operator.

fn not(self) -> Self

Performs the unary ! operation.

impl PartialEq for Choice

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

impl Copy for Choice

impl Eq for Choice

impl StructuralPartialEq for Choice
