Implementations
sourceimpl Signature
impl Signature
sourcepub fn new<C: Into<Cow<'static, [ValueType]>>>(
params: C,
return_type: Option<ValueType>
) -> Signature
pub fn new<C: Into<Cow<'static, [ValueType]>>>(
params: C,
return_type: Option<ValueType>
) -> Signature
Creates new signature with givens parameter types and optional return type.
Examples
use wasmi::{Signature, ValueType};
// s1: (i32) -> ()
let s1 = Signature::new(&[ValueType::I32][..], None);
// s2: () -> i32
let s2 = Signature::new(&[][..], Some(ValueType::I32));
// s3: (I64) -> ()
let dynamic_params = vec![ValueType::I64];
let s3 = Signature::new(dynamic_params, None);
sourcepub fn return_type(&self) -> Option<ValueType>
pub fn return_type(&self) -> Option<ValueType>
Returns return type of this signature.
