Implementations§
source§impl<F> MessageSpec<F>where
F: Form,
impl<F> MessageSpec<F>where
F: Form,
sourcepub fn from_label(
label: <F as Form>::String
) -> MessageSpecBuilder<F, Missing<Selector>, Missing<Mutates>, Missing<IsPayable>, Missing<Returns>>
pub fn from_label(
label: <F as Form>::String
) -> MessageSpecBuilder<F, Missing<Selector>, Missing<Mutates>, Missing<IsPayable>, Missing<Returns>>
Creates a new message spec builder.

impl<F> MessageSpec<F>where
F: Form,
sourcepub fn label(&self) -> &F::String
pub fn label(&self) -> &F::String
Returns the label of the message.
In case of trait provided messages and constructors the prefix by convention in ink! is the label of the trait.
sourcepub fn mutates(&self) -> bool
pub fn mutates(&self) -> bool
Returns true if the message is allowed to mutate the contract state.
sourcepub fn args(&self) -> &[MessageParamSpec<F>]
pub fn args(&self) -> &[MessageParamSpec<F>]
Returns the parameters of the message.
sourcepub fn return_type(&self) -> &ReturnTypeSpec<F>
pub fn return_type(&self) -> &ReturnTypeSpec<F>
Returns the return type of the message.
