source · [−]Attribute Macros
Entry point for use openbrush’s macros in ink! smart contracts.
This macro only checks that some free-standing function satisfies a set of rules.
Macro calls every modifier function by passing self and the code of function’s body. It means that modifiers must be available in the scope of the marked method.
Defines extensible trait in the scope of openbrush::contract.
It is a common rust trait, so you can use any features of rust inside of this trait.
If this trait contains some methods marked with #[ink(message)] or #[ink(constructor)] attributes,
this macro will extract these attributes and will put them into a separate trait
(the separate trait only is used to call methods from the original trait), but the macro will not touch methods.
That macro implemented SpreadLayout, SpreadAllocate, StorageLayout and OccupyStorage
with a specified storage key instead of the default one (All data is stored under
the provided storage key).
This macro allows you to define a wrapper type for traits defined via
#[openbrush::trait_definition].
It is a wrapper for AccountId that knows how to do cross-contract calls to another contract.
Derive Macros
The macro implements openbrush::traits::Storage and openbrush::traits::OccupiedStorage
traits for each field marked by #[storage_field] attribute. Each field’s type should implement
the openbrush::traits::OccupyStorage trait with a unique storage key. Each occupied storage
key should be unique for each type otherwise compilation will fail.
