Struct llvm_rs::types::StructType

pub struct StructType(_);

A structure type, such as a tuple or struct.

Implementations

impl StructType

pub fn new<'a>(
    context: &'a Context,
    fields: &[&'a Type],
    packed: bool
) -> &'a StructType

Make a new struct with the given fields and packed representation.

pub fn new_named<'a>(
    context: &'a Context,
    name: &str,
    fields: &[&'a Type],
    packed: bool
) -> &'a StructType

Make a new named struct with the given fields and packed representation.

pub fn new_opaque<'a>(context: &'a Context, name: &str) -> &'a StructType

Make a new named struct without defining its fields yet.

You can use this opaque struct without defining its fields (for creating recursive types, etc.). When you want to define its fields (which may include itself), use set_elements().

pub fn set_elements<'a>(
    &self,
    fields: &[&'a Type],
    packed: bool
) -> Result<(), ()>

Set the elements that make up this struct.

Can only be called once, and only on a StructType created through the new_opaque() function. Returns Err(()) if the struct is not opaque.

pub fn get_elements(&self) -> Vec<&Type>

Returns the elements that make up this struct.

Methods from Deref<Target = Type>

pub fn is_sized(&self) -> bool

Returns true if the size of the type is known at compile-time.

This is equivalent to the type implementing Sized in Rust

pub fn is_function(&self) -> bool

Returns true if this type is a function.

This is equivalent to FunctionType::is.

pub fn is_struct(&self) -> bool

Returns true if this type is a struct.

This is equivalent to StructType::is.

pub fn is_void(&self) -> bool

Returns true if this type is void.

pub fn is_pointer(&self) -> bool

Returns true if this type is a pointer.

This is equivalent to PointerType::is.

pub fn is_integer(&self) -> bool

Returns true if this type is an integer.

pub fn is_float(&self) -> bool

Returns true if this type is any floating-point number.

pub fn get_size(&self, target: &TargetData) -> usize

Trait Implementations

impl Debug for StructType

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

Formats the value using the given formatter.

impl Deref for StructType

type Target = Type

The resulting type after dereferencing.

fn deref(&self) -> &Type

Dereferences the value.

impl<'a> From<&'a StructType> for LLVMTypeRef

fn from(ty: &'a StructType) -> LLVMTypeRef

Converts to this type from the input type.

impl<'a> From<&'a mut StructType> for LLVMTypeRef

fn from(ty: &'a mut StructType) -> LLVMTypeRef

Converts to this type from the input type.

impl<'a> From<*mut LLVMType> for &'a StructType

fn from(ty: LLVMTypeRef) -> &'a StructType

Converts to this type from the input type.

impl<'a> From<*mut LLVMType> for &'a mut StructType

fn from(ty: LLVMTypeRef) -> &'a mut StructType

Converts to this type from the input type.

impl GetContext for StructType

fn get_context(&self) -> &Context

Returns a reference to the context that owns this value.

impl<'a> PartialEq<StructType> for &'a StructType

fn eq(&self, other: &StructType) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialEq<StructType> for StructType

fn eq(&self, other: &StructType) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Sub<Type> for StructType

fn is(ty: &Type) -> bool

Check if the given super value is an instance of this type.

fn from_super(c: &T) -> Option<&Self>

Attempt to cast the given super value into an instance of this type.

fn to_super(&self) -> &T

Cast this value to a super value.
