Struct wasmi::Signature [−][src]
pub struct Signature { /* fields omitted */ }
Signature of a function.
Signature of a function consists of zero or more parameter types and zero or one return type.
Two signatures are considered equal if they have equal list of parameters and equal return types.
Methods
impl Signature
[src]
impl Signature
pub fn new<C: Into<Cow<'static, [ValueType]>>>(
params: C,
return_type: Option<ValueType>
) -> Signature
[src]
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);
pub fn params(&self) -> &[ValueType]
[src]
pub fn params(&self) -> &[ValueType]
Returns parameter types of this signature.
pub fn return_type(&self) -> Option<ValueType>
[src]
pub fn return_type(&self) -> Option<ValueType>
Returns return type of this signature.
