Struct ParamSignature

pub struct ParamSignature {
    pub ty: ConcreteTypeId,
    pub allow_deferred: bool,
    pub allow_add_const: bool,
    pub allow_const: bool,
}

Information regarding a parameter of the libfunc.

Fields

ty: ConcreteTypeId

allow_add_const: bool

Whether the libfunc argument can be an expression of the form [ap + i] + const.

allow_const: bool

Whether the libfunc argument can be a constant.
