Struct sp_wasm_interface::Signature

pub struct Signature {
    pub args: Cow<'static, [ValueType]>,
    pub return_value: Option<ValueType>,
}

The Signature of a function

Fields

args: Cow<'static, [ValueType]>

The arguments of a function.

return_value: Option<ValueType>

The optional return value of a function.

Implementations

impl Signature

pub fn new<T: Into<Cow<'static, [ValueType]>>>(
    args: T,
    return_value: Option<ValueType>
) -> Self

Create a new instance of Signature.

pub fn new_with_args<T: Into<Cow<'static, [ValueType]>>>(args: T) -> Self

Create a new instance of Signature with the given args and without any return value.

Trait Implementations

impl Clone for Signature

fn clone(&self) -> Signature

Returns a copy of the value.

pub 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 From<&'_ Signature> for Signature

fn from(sig: &Signature) -> Self

Performs the conversion.
