Enum RedTy 

pub enum RedTy<'db> {
    Error(Reported),
    Named(SymTyName<'db>, Vec<SymGenericTerm<'db>>),
    Never,
    Infer(InferVarIndex),
    Var(SymVariable<'db>),
    Perm,
}

A “red(uced) type”– captures just the type layout part of a SymGenericTerm.

Variants

Error(Reported)

An error occurred while processing this type.

Named(SymTyName<'db>, Vec<SymGenericTerm<'db>>)

A named type.

Never

Never type.

Infer(InferVarIndex)

An inference variable.

Var(SymVariable<'db>)

A variable.

Perm

A permission – this variant occurs when we convert a SymPerm to a RedTy.

Implementations

impl<'db> RedTy<'db>

pub fn fallback(_db: &'db dyn Db) -> Self

Inference fallback

pub fn into_sym_ty(self, db: &'db dyn Db) -> SymTy<'db>

Trait Implementations

impl<'db> Clone for RedTy<'db>

fn clone(&self) -> RedTy<'db>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'db> Debug for RedTy<'db>

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

Formats the value using the given formatter.

impl<'db> Err<'db> for RedTy<'db>

fn err(_db: &'db dyn Db, reported: Reported) -> Self

impl<'db> Hash for RedTy<'db>

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<'db> Ord for RedTy<'db>

fn cmp(&self, other: &RedTy<'db>) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl<'db> PartialEq for RedTy<'db>

fn eq(&self, other: &RedTy<'db>) -> 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<'db> PartialOrd for RedTy<'db>

fn partial_cmp(&self, other: &RedTy<'db>) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl<'db> RedTyExt<'db> for RedTy<'db>

fn display<'a>(&'a self, env: &'a Env<'db>) -> impl Display

impl<'db> Serialize for RedTy<'db>

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl<'db> Update for RedTy<'db>

unsafe fn maybe_update(old_pointer_: *mut Self, new_value_: Self) -> bool

Returns

impl<'db> Eq for RedTy<'db>
