Expand description

Describes the contract message return type.

Implementations§

source§

impl<F> ReturnTypeSpec<F>where F: Form, TypeSpec<F>: Default,

source

pub fn new<T>(ty: T) -> Selfwhere T: Into<TypeSpec<F>>,

Creates a new return type specification from the given type or None.

Examples

source

pub fn ret_type(&self) -> &TypeSpec<F>

Returns the return type
