Struct ink_metadata::ConstructorSpecBuilder
source · pub struct ConstructorSpecBuilder<F: Form, Selector, IsPayable, Returns> { /* private fields */ }
Expand description
A builder for constructors.
Developer Note
Some fields are guarded by a type-state pattern to fail at compile-time instead of at run-time. This is useful to better debug code-gen macros.
Implementations§
source§impl<F, P, R> ConstructorSpecBuilder<F, Missing<Selector>, P, R>where
F: Form,
impl<F, P, R> ConstructorSpecBuilder<F, Missing<Selector>, P, R>where
F: Form,
sourcepub fn selector(
self,
selector: [u8; 4]
) -> ConstructorSpecBuilder<F, Selector, P, R>
pub fn selector(
self,
selector: [u8; 4]
) -> ConstructorSpecBuilder<F, Selector, P, R>
Sets the function selector of the message.
source§impl<F, S, R> ConstructorSpecBuilder<F, S, Missing<IsPayable>, R>where
F: Form,
impl<F, S, R> ConstructorSpecBuilder<F, S, Missing<IsPayable>, R>where
F: Form,
sourcepub fn payable(
self,
is_payable: bool
) -> ConstructorSpecBuilder<F, S, IsPayable, R>
pub fn payable(
self,
is_payable: bool
) -> ConstructorSpecBuilder<F, S, IsPayable, R>
Sets if the constructor is payable, thus accepting value for the caller.

F: Form,
impl<F, S, P> ConstructorSpecBuilder<F, S, P, Missing<Returns>>where

sourcepub fn returns(
self,
return_type: ReturnTypeSpec<F>
) -> ConstructorSpecBuilder<F, S, P, Returns>
pub fn returns(
self,
return_type: ReturnTypeSpec<F>
) -> ConstructorSpecBuilder<F, S, P, Returns>
Sets the return type of the message.

impl<F, S, P, R> ConstructorSpecBuilder<F, S, P, R>where
F: Form,
sourcepub fn args<A>(self, args: A) -> Selfwhere
A: IntoIterator<Item = MessageParamSpec<F>>,
pub fn args<A>(self, args: A) -> Selfwhere
A: IntoIterator<Item = MessageParamSpec<F>>,
Sets the input arguments of the message specification.

sourcepub fn done(self) -> ConstructorSpec<F>
pub fn done(self) -> ConstructorSpec<F>
Finishes construction of the constructor.
