Module foundationdb::transaction

Implementations of the FDBTransaction C API

https://apple.github.io/foundationdb/api-c.html#transaction

Structs

GetAddressResult

Represents the data of a Transaction::get_addresses_for_key

GetKeyResult

Represents the data of a Transaction::get_key

GetRangeResult

Represents the data of a Transaction::get_range. The result might not contains all results specified by Transaction::get_range. A caller can test if the result is complete by either checking GetRangeResult::key_values().more() is true, or checking GetRangeResult::next is not None. If a caller wants to fetch all matching results, they should call Transcation::get_range with following RangeOption returned by GetRangeResult::next. The caller might want to use Transaction::get_ranges which will fetch all results until it finishes.

GetResult

Represents the data of a Transaction::get

RangeOption

RangeOption represents a query parameters for range scan query.

RangeOptionBuilder

A Builder with which options need to used for a range query.

RangeStream

RangeStream represents a stream of GetRangeResult

Transaction

In FoundationDB, a transaction is a mutable snapshot of a database.

TrxCommit

A future result of a Transaction::commit

TrxErrFuture

Abstraction over fdb_transaction_on_err.

TrxGet

A future results of a get operation

TrxGetAddressesForKey

A future result of a Transaction::get_addresses_for_key

TrxGetKey

A future results of a get_key operation

TrxGetRange

A future results of a get_range operation

TrxReadVersion

A future result of a Transaction::watch

TrxVersionstamp

A future result of a Transaction::watch

TrxWatch

A future result of a Transaction::watch

Versionstamp

A versionstamp is a 10 byte, unique, monotonically (but not sequentially) increasing value for each committed transaction. The first 8 bytes are the committed version of the database. The last 2 bytes are monotonic in the serialization order for transactions.
