Enum LinearKind 

pub enum LinearKind {
    Unrestricted,
    Linear,
    Affine,
    Relevant,
}

The kind of linearity constraint.

Variants

Unrestricted

Unrestricted: can be used any number of times (standard types)

Linear

Linear: must be used exactly once

Affine

Affine: can be used at most once (can be dropped)

Relevant

Relevant: must be used at least once (can be copied)

Implementations

impl LinearKind

pub fn allows_copy(&self) -> bool

Check if this kind allows copying.

pub fn allows_drop(&self) -> bool

Check if this kind allows dropping without use.

pub fn requires_use(&self) -> bool

Check if this kind requires at least one use.

pub fn limits_use(&self) -> bool

Check if this kind limits to at most one use.

pub fn join(&self, other: &LinearKind) -> LinearKind

Get the join (least upper bound) of two kinds.

pub fn meet(&self, other: &LinearKind) -> LinearKind

Get the meet (greatest lower bound) of two kinds.

Trait Implementations

impl Clone for LinearKind

fn clone(&self) -> LinearKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LinearKind

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

Formats the value using the given formatter.

impl Display for LinearKind

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

Formats the value using the given formatter.

impl Hash for LinearKind

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 LinearKind

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