Struct TypeRef 

pub struct TypeRef {
    pub scope: ModPath,
    pub name: ModPath,
    pub params: Arc<[Type]>,
    pub pos: Option<SourcePosition>,
    pub ori: Option<Arc<Origin>>,
}

A reference to a named typedef, e.g. Foo or Result<i64, string>. pos and ori are IDE metadata recording where this reference was written in source — they’re populated by the parser and ignored for type-system equality, ordering and hashing so they don’t affect type identity.

Fields

scope: ModPath

name: ModPath

params: Arc<[Type]>

pos: Option<SourcePosition>

ori: Option<Arc<Origin>>

Implementations

impl TypeRef

pub fn synthetic(scope: ModPath, name: ModPath, params: Arc<[Type]>) -> Self

Build a TypeRef with no source-position info — for synthetic type references created during type inference, set operations, stdlib type literals, etc.

Trait Implementations

impl Clone for TypeRef

fn clone(&self) -> TypeRef

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TypeRef

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

Formats the value using the given formatter.

impl Default for TypeRef

fn default() -> Self

Returns the “default value” for a type.

impl Ord for TypeRef

fn cmp(&self, other: &Self) -> 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 PartialEq for TypeRef

fn eq(&self, other: &Self) -> 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 PartialOrd for TypeRef

fn partial_cmp(&self, other: &Self) -> 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.
