Struct cranelift_codegen::ir::Signature

pub struct Signature {
    pub params: Vec<AbiParam>,
    pub returns: Vec<AbiParam>,
    pub call_conv: CallConv,
}

Function signature.

The function signature describes the types of formal parameters and return values along with other details that are needed to call a function correctly.

A signature can optionally include ISA-specific ABI information which specifies exactly how arguments and return values are passed.

Fields

params: Vec<AbiParam>

The arguments passed to the function.

returns: Vec<AbiParam>

Values returned from the function.

call_conv: CallConv

Calling convention.

Methods

impl Signature

pub fn new(call_conv: CallConv) -> Self

Create a new blank signature.

pub fn clear(&mut self, call_conv: CallConv)

Clear the signature so it is identical to a fresh one returned by new().

pub fn display<'a, R: Into<Option<&'a RegInfo>>>(
    &'a self,
    regs: R
) -> DisplaySignature<'a>

Return an object that can display self with correct register names.

pub fn special_param_index(&self, purpose: ArgumentPurpose) -> Option<usize>

Find the index of a presumed unique special-purpose parameter.

Trait Implementations

impl Clone for Signature

fn clone(&self) -> Signature

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Signature

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

Formats the value using the given formatter.

impl Display for Signature

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

Formats the value using the given formatter.

impl PartialEq<Signature> for Signature

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

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

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

This method tests for !=.

impl Eq for Signature

impl Hash for Signature

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given [Hasher].

fn hash_slice<H>(data: &[Self], state: &mut H) where
    H: Hasher, 

Feeds a slice of this type into the given [Hasher].
