Tables
See also: https://doc.cuprate.org/cuprate_blockchain/tables & https://doc.cuprate.org/cuprate_blockchain/types.
The CamelCase names of the table headers documented here (e.g. TxIds) are the actual type name of the table within cuprate_blockchain.
Note that words written within code blocks mean that it is a real type defined and usable within cuprate_blockchain. Other standard types like u64 and type aliases (TxId) are written normally.
Within cuprate_blockchain::tables, the below table is essentially defined as-is with a macro.
Many of the data types stored are the same data types, although are different semantically, as such, a map of aliases used and their real data types is also provided below.
| Alias | Real Type |
|---|---|
| BlockHeight, Amount, AmountIndex, TxId, UnlockTime | u64 |
| BlockHash, KeyImage, TxHash, PrunableHash | [u8; 32] |
| Table | Key | Value | Description |
|---|---|---|---|
BlockHeaderBlobs | BlockHeight | StorableVec<u8> | Maps a block's height to a serialized byte form of its header |
BlockTxsHashes | BlockHeight | StorableVec<[u8; 32]> | Maps a block's height to the block's transaction hashes |
BlockHeights | BlockHash | BlockHeight | Maps a block's hash to its height |
BlockInfos | BlockHeight | BlockInfo | Contains metadata of all blocks |
KeyImages | KeyImage | () | This table is a set with no value, it stores transaction key images |
NumOutputs | Amount | u64 | Maps an output's amount to the number of outputs with that amount |
Outputs | PreRctOutputId | Output | This table contains legacy CryptoNote outputs which have clear amounts. This table will not contain an output with 0 amount. |
PrunedTxBlobs | TxId | StorableVec<u8> | Contains pruned transaction blobs (even if the database is not pruned) |
PrunableTxBlobs | TxId | StorableVec<u8> | Contains the prunable part of a transaction |
PrunableHashes | TxId | PrunableHash | Contains the hash of the prunable part of a transaction |
RctOutputs | AmountIndex | RctOutput | Contains RingCT outputs mapped from their global RCT index |
TxBlobs | TxId | StorableVec<u8> | Serialized transaction blobs (bytes) |
TxIds | TxHash | TxId | Maps a transaction's hash to its index/ID |
TxHeights | TxId | BlockHeight | Maps a transaction's ID to the height of the block it comes from |
TxOutputs | TxId | StorableVec<u64> | Gives the amount indices of a transaction's outputs |
TxUnlockTime | TxId | UnlockTime | Stores the unlock time of a transaction (only if it has a non-zero lock time) |
