Crate ic_ledger_types

A library of types to communicate with the ICP ledger canister.

Structs

• AccountBalanceArgs
  Arguments for the account_balance call.
• AccountIdentifier
  AccountIdentifier is a 32-byte array. The first 4 bytes is a big-endian encoding of a CRC32 checksum of the last 28 bytes.
• ArchivedBlockRange
  A function that can be called to retrieve a range of archived blocks.
• Block
  A single record in the ledger.
• BlockRange
  A prefix of the block range specified in the get_blocks and query_archived_blocks function.
• GetBlocksArgs
  Arguments for the get_blocks function.
• Memo
  An arbitrary number associated with a transaction. The caller can set it in a transfer call as a correlation identifier.
• QueryArchiveFn
  Function type used by query_blocks for fetching blocks from the archive. Has the signature (GetBlocksArgs) -> (GetBlocksResult).
• QueryBlocksResponse
  Return type for the query_blocks function.
• Subaccount
  Subaccount is an arbitrary 32-byte byte array. Ledger uses subaccounts to compute account address, which enables one principal to control multiple ledger accounts.
• Symbol
  Return type of the token_symbol function.
• Timestamp
  Number of nanoseconds from the UNIX epoch in UTC timezone.
• Tokens
  A type for representing amounts of Tokens.
• Transaction
  A recorded ledger transaction.
• TransferArgs
  Arguments for the transfer call.

Enums

• GetBlocksError
  An error indicating that the arguments passed to get_blocks or query_archived_blocks were invalid.
• Operation
  The content of a ledger transaction.
• TransferError
  Error of the transfer call.

Constants

• DEFAULT_FEE
  The default fee for ledger transactions.
• DEFAULT_SUBACCOUNT
  The subaccont that is used by default.
• MAINNET_CYCLES_MINTING_CANISTER_ID
  Id of the cycles minting canister on the IC.
• MAINNET_GOVERNANCE_CANISTER_ID
  Id of the governance canister on the IC.
• MAINNET_LEDGER_CANISTER_ID
  Id of the ledger canister on the IC.

Functions

• account_balance
  Calls the “account_balance” method on the specified canister.
• query_archived_blocks
  Continues a query started in query_blocks by calling its returned archive function.
• query_blocks
  Calls the “query_block” method on the specified canister.
• token_symbol
  Calls the “token_symbol” method on the specified canister.
• transfer
  Calls the “transfer” method on the specified canister.

Type Definitions

• BlockIndex
  The sequence number of a block in the Tokens ledger blockchain.
• GetBlocksResult
  The return type of get_blocks.
• TransferResult
  Result of the transfer call.
