Module call

APIs to make and manage calls in the canister.

Structs

• ArgDecoderConfig
  Config to control the behavior of decoding canister endpoint arguments.
• CallReplyWriter
  An io::Write for message replies.
• ManualReply
  Pretends to have the Candid type T, but unconditionally errors when serialized.

Enums

• RejectionCode
  Rejection code from calling another canister.

Functions

• accept_message
  Accepts the ingress message.
• arg_data
  Returns the argument data in the current call. Traps if the data cannot be decoded.
• arg_data_raw
  Returns the argument data as bytes.
• arg_data_raw_size
  Gets the len of the raw-argument-data-bytes.
• call
  Performs an asynchronous call to another canister.
• call_raw
  Performs an asynchronous call to another canister and pay cycles at the same time.
• call_raw128
  Performs an asynchronous call to another canister and pay cycles (in u128) at the same time.
• call_with_config
  Performs an asynchronous call to another canister and pay cycles (in u128). It also allows setting a quota for decoding the return values. The decoding quota is strongly recommended when calling third-party or untrusted canisters.
• call_with_payment
  Performs an asynchronous call to another canister and pay cycles at the same time.
• call_with_payment128
  Performs an asynchronous call to another canister and pay cycles (in u128) at the same time.
• is_recovering_from_trap
  Tells you whether the current async fn is being canceled due to a trap/panic.
• method_name
  Returns the name of current canister method.
• msg_cycles_accept
  Moves cycles from the call to the canister balance.
• msg_cycles_accept128
  Moves cycles from the call to the canister balance.
• msg_cycles_available
  Returns the amount of cycles that were transferred by the caller of the current call, and is still available in this message.
• msg_cycles_available128
  Returns the amount of cycles that were transferred by the caller of the current call, and is still available in this message.
• msg_cycles_refunded
  Returns the amount of cycles that came back with the response as a refund.
• msg_cycles_refunded128
  Returns the amount of cycles that came back with the response as a refund.
• notify
  Like notify_with_payment128, but sets the payment to zero.
• notify_raw
  Like notify, but sends the argument as raw bytes, skipping Candid serialization.
• notify_with_payment128
  Sends a one-way message with payment cycles attached to it that invokes method with arguments args on the principal identified by id, ignoring the reply.
• performance_counterDeprecated
  Gets the value of specified performance counter
• reject
  Rejects the current call with the message.
• reject_code
  Returns the rejection code for the call.
• reject_message
  Returns the rejection message.
• reply
  Replies to the current call with a candid argument.
• reply_raw
  Replies with the bytes passed
• result
  Returns a result that maps over the call

Type Aliases

• CallResult
  The result of a Call.
