Required Methods§

Source

fn instance_id(&self) -> InstanceId

Contract instance identifier.

Source

fn instance_address(&self) -> &Address

Contract instance address.

Source

fn caller_address(&self) -> &Address

Caller address.

Source

fn deposited_tokens(&self) -> &[BaseUnits]

Tokens deposited by the caller.

Source

fn is_read_only(&self) -> bool

Whether the call is read-only and must not make any storage modifications.

Source

fn call_format(&self) -> CallFormat

Call format.

Source

fn emit_message(&mut self, msg: Message)

Emits a message.

Source

fn emit_event<E: Event>(&mut self, event: E)

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
