Struct llvm_ir::types::Types

pub struct Types { /* fields omitted */ }

Holds a reference to all of the Types used in the Module, and facilitates lookups so you can get a TypeRef to the Type you want.

Implementations

impl Types

pub fn type_of<T: Typed + ?Sized>(&self, t: &T) -> TypeRef

Get the type of anything that is Typed

pub fn void(&self) -> TypeRef

Get the void type

pub fn int(&self, bits: u32) -> TypeRef

Get the integer type of the specified size (in bits)

pub fn bool(&self) -> TypeRef

Get the boolean type (i1)

pub fn i8(&self) -> TypeRef

Get the 8-bit integer type

pub fn i16(&self) -> TypeRef

Get the 16-bit integer type

pub fn i32(&self) -> TypeRef

Get the 32-bit integer type

pub fn i64(&self) -> TypeRef

Get the 64-bit integer type

pub fn pointer_to(&self, pointee_type: TypeRef) -> TypeRef

Get a pointer type in the default address space (0)

pub fn pointer_in_addr_space(
    &self,
    pointee_type: TypeRef,
    addr_space: AddrSpace
) -> TypeRef

Get a pointer type in the specified address space

pub fn fp(&self, fpt: FPType) -> TypeRef

Get a floating-point type

pub fn single(&self) -> TypeRef

Get the single-precision floating-point type

pub fn double(&self) -> TypeRef

Get the double-precision floating-point type

pub fn func_type(
    &self,
    result_type: TypeRef,
    param_types: Vec<TypeRef>,
    is_var_arg: bool
) -> TypeRef

Get a function type

pub fn vector_of(&self, element_type: TypeRef, num_elements: usize) -> TypeRef

pub fn array_of(&self, element_type: TypeRef, num_elements: usize) -> TypeRef

Get an array type

pub fn struct_of(&self, element_types: Vec<TypeRef>, is_packed: bool) -> TypeRef

Get a struct type

pub fn named_struct(&self, name: &str) -> TypeRef

Get the TypeRef for the struct with the given name.

Note that this gives a NamedStructType. To get the actual definition of a named struct (the NamedStructDef), use named_struct_def().

pub fn named_struct_def(&self, name: &str) -> Option<&NamedStructDef>

Get the NamedStructDef for the struct with the given name, or None if there is no struct by that name.

Note that this gives a NamedStructDef. To get the NamedStructType for a name, use named_struct().

pub fn all_struct_names(&self) -> impl Iterator<Item = &String>

Get the names of all the named structs

pub fn add_named_struct_def(&mut self, name: String, def: NamedStructDef)

Add the given NamedStructDef as the definition of the struct with the given name.

Panics if that name already had a definition.

pub fn remove_named_struct_def(&mut self, name: &str) -> bool

Remove the definition of the struct with the given name.

Returns true if the definition was removed, or false if no definition existed.

pub fn x86_mmx(&self) -> TypeRef

Get the X86_MMX type

pub fn metadata_type(&self) -> TypeRef

Get the metadata type

pub fn label_type(&self) -> TypeRef

Get the label type

pub fn token_type(&self) -> TypeRef

Get the token type

pub fn get_for_type(&self, ty: &Type) -> TypeRef

Get a TypeRef for the given Type

impl Types

pub fn blank_for_testing() -> Self

Get a blank Types containing essentially no types. This function is intended only for use in testing; it’s probably not useful otherwise.

Trait Implementations

impl Clone for Types

fn clone(&self) -> Types

Returns a copy of the value.

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

Performs copy-assignment from source.
