Struct VariableId 

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

Stable handle to a decision variable.

Implementations

impl VariableId

pub const fn key(self) -> VariableKey

Returns the underlying arena key.

pub const fn from_key(key: VariableKey) -> Self

Creates an id from an arena key.

Trait Implementations

impl Clone for VariableId

fn clone(&self) -> VariableId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for VariableId

impl Debug for VariableId

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

Formats the value using the given formatter.

impl Eq for VariableId

impl Hash for VariableId

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for VariableId

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