Enum EffectScheme 

pub enum EffectScheme {
    Concrete(EffectSet),
    Variable(EffectVar),
    Union(Box<EffectScheme>, Box<EffectScheme>),
}

Effect scheme for effect polymorphism (analogous to type schemes)

Variants

Concrete(EffectSet)

Concrete effect set

Variable(EffectVar)

Effect variable (for polymorphism)

Union(Box<EffectScheme>, Box<EffectScheme>)

Union of effect schemes

Implementations

impl EffectScheme

pub fn concrete(effects: EffectSet) -> Self

Create a concrete effect scheme

pub fn variable(name: impl Into<String>) -> Self

Create an effect variable

pub fn union(e1: EffectScheme, e2: EffectScheme) -> Self

Create a union of two effect schemes

pub fn substitute(&self, subst: &EffectSubstitution) -> EffectScheme

Substitute effect variables with concrete effect sets

pub fn evaluate(&self, subst: &EffectSubstitution) -> Result<EffectSet, IrError>

Evaluate to a concrete effect set (if possible)

Trait Implementations

impl Clone for EffectScheme

fn clone(&self) -> EffectScheme

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EffectScheme

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for EffectScheme

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for EffectScheme

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

Formats the value using the given formatter.

impl PartialEq for EffectScheme

fn eq(&self, other: &EffectScheme) -> 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 EffectScheme

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for EffectScheme
