Struct BuiltinTypeDef 

pub struct BuiltinTypeDef {
    pub name: &'static str,
    pub fields: &'static [BuiltinField],
    pub is_copy: bool,
    pub drop_fn: Option<&'static str>,
    pub operators: &'static [BuiltinOperator],
    pub associated_fns: &'static [BuiltinAssociatedFn],
    pub methods: &'static [BuiltinMethod],
}

Definition of a built-in type.

This describes everything the compiler needs to know about a built-in type: its layout (fields), behavior (operators), and available operations (methods).

Fields

name: &'static str

Type name as it appears in source code (e.g., “String”)

fields: &'static [BuiltinField]

Fields that make up the struct layout

is_copy: bool

Whether this type is Copy (can be implicitly duplicated)

drop_fn: Option<&'static str>

Runtime function to call for drop, if any

operators: &'static [BuiltinOperator]

Supported operators and their implementations

associated_fns: &'static [BuiltinAssociatedFn]

Associated functions (e.g., String::new)

methods: &'static [BuiltinMethod]

Instance methods (e.g., s.len())

Implementations

impl BuiltinTypeDef

pub fn slot_count(&self) -> u32

Get the number of slots this type uses in the ABI.

Each field uses one slot (all fields are currently scalar types).

pub fn find_associated_fn(&self, name: &str) -> Option<&BuiltinAssociatedFn>

Find an associated function by name.

pub fn find_method(&self, name: &str) -> Option<&BuiltinMethod>

Find a method by name.

pub fn find_operator(&self, op: BinOp) -> Option<&BuiltinOperator>

Find an operator implementation.

pub fn supports_operator(&self, op: BinOp) -> bool

Check if this type supports a given operator.

Trait Implementations

impl Clone for BuiltinTypeDef

fn clone(&self) -> BuiltinTypeDef

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BuiltinTypeDef

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

Formats the value using the given formatter.
