Functions

balance

The balance of the canister.

call

Perform the call and return the response.

call_raw

Perform a call.

call_with_payment

caller

The caller who has invoked this method on the canister.

data_certificate

Returns the data certificate authenticating certified_data set by this canister.

deleteDeprecated

Remove the data associated with the given data type.

getDeprecated

Return the data associated with the given type. If the data is not present the default value of the type is returned.

get_maybeDeprecated

Return the data that does not implement Default.

get_mutDeprecated

Return a mutable reference to the given data type, if the data is not present the default value of the type is constructed and stored. The changes made to the data during updates is preserved.

id

ID of the current canister.

maybe_with

Like with, but does not initialize the data with the default value and simply returns None, if there is no value associated with the type.

maybe_with_mut

Like with_mut, but does not initialize the data with the default value and simply returns None, if there is no value associated with the type.

msg_cycles_accept

Accept the given amount of cycles, returns the actual amount of accepted cycles.

msg_cycles_available

Return the number of available cycles that is sent by the caller.

msg_cycles_refunded

Return the cycles that were sent back by the canister that was just called. This method should only be called right after an inter-canister call.

print
