Expand description

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.

Implementations

Create a new blank signature.

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

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

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

Does this signature have a parameter whose ArgumentPurpose is purpose?

Does this signature have a return whose ArgumentPurpose is purpose?

How many special parameters does this function have?

How many special returns does this function have?

Does this signature take an struct return pointer parameter?

Does this return more than one normal value? (Pre-struct return legalization)
