Struct llvm_rs::types::FunctionType

pub struct FunctionType(_);

A function signature type.

Implementations

impl FunctionType

pub fn new<'a>(ret: &'a Type, args: &[&'a Type]) -> &'a FunctionType

Make a new function signature with the return type and arguments given.

pub fn num_params(&self) -> usize

Returns the number of parameters this signature takes.

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

Returns a vector of this signature’s parameters’ types.

pub fn get_return(&self) -> &Type

Returns the type that this function returns.

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 FunctionType

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

Formats the value using the given formatter.

impl Deref for FunctionType

type Target = Type

The resulting type after dereferencing.

fn deref(&self) -> &Type

Dereferences the value.

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

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

Converts to this type from the input type.

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

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

Converts to this type from the input type.

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

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

Converts to this type from the input type.

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

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

Converts to this type from the input type.

impl GetContext for FunctionType

fn get_context(&self) -> &Context

Returns a reference to the context that owns this value.

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

fn eq(&self, other: &FunctionType) -> 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<FunctionType> for FunctionType

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

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.
