}

Enhanced type system used throughout RunMat for HIR and builtin functions Designed to mirror Value variants for better type inference and LSP support

Variants

Int

Integer number type

Num

Floating-point number type

Bool

Boolean type

Logical

Logical array type (N-D boolean array)

String

String type

Tensor

Tensor type with optional shape information (column-major semantics in runtime)

Fields

shape: Option<Vec<Option<usize>>>

Optional full shape; None means unknown/dynamic; individual dims can be omitted by using None

Cell

Cell array type with optional element type information

Fields

element_type: Option<Box<Type>>

Optional element type (None means mixed/unknown)

length: Option<usize>

Optional length (None means unknown/dynamic)

Function

Function type with parameter and return types

Fields

params: Vec<Type>

Parameter types

returns: Box<Type>

Return type

Void

Void type (no value)

Unknown

Unknown type (for type inference)

Union(Vec<Type>)

Union type (multiple possible types)

Struct

Struct-like type with optional known field set (purely for inference)

Fields

known_fields: Option<Vec<String>>

Optional set of known field names observed via control-flow (None = unknown fields)

Implementations

impl Type

pub fn tensor() -> Self

Create a tensor type with unknown shape

pub fn tensor_with_shape(shape: Vec<usize>) -> Self

Create a tensor type with known shape

pub fn cell() -> Self

Create a cell array type with unknown element type

pub fn cell_of(element_type: Type) -> Self

Create a cell array type with known element type

pub fn is_compatible_with(&self, other: &Type) -> bool

Check if this type is compatible with another type

pub fn unify(&self, other: &Type) -> Type

Get the most specific common type between two types

pub fn from_value(value: &Value) -> Type

Infer type from a Value

Trait Implementations

impl Clone for Type

fn clone(&self) -> Type

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Type

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Type

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Type

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

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 Type

impl StructuralPartialEq for Type
