Enum Multiplicity 

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

Multiplicity: how many times a value can be used.

Variants

Linear

Linear: must be used exactly once (1)

Affine

Affine: must be used at most once (0..1)

Relevant

Relevant: must be used at least once (1..)

Unrestricted

Unrestricted: can be used any number of times (0..)

Implementations

impl Multiplicity

pub fn allows(&self, n: usize) -> bool

Check if a value with this multiplicity can be used n times

pub fn is_linear(&self) -> bool

Check if this is linear (exactly once)

pub fn is_unrestricted(&self) -> bool

Check if this is unrestricted (any number of times)

pub fn combine(&self, other: &Multiplicity) -> Multiplicity

Combine multiplicities (for products/tuples)

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

Join multiplicities (for sums/unions)

Trait Implementations

impl Clone for Multiplicity

fn clone(&self) -> Multiplicity

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Multiplicity

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Multiplicity

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Multiplicity

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

Formats the value using the given formatter.

impl Hash for Multiplicity

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 Multiplicity

fn eq(&self, other: &Multiplicity) -> 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 Serialize for Multiplicity

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
