Crate possum
Source - concurrency
- env
- sys
- Exposes required lower-level OS primitives for sparse files, block cloning, and file locking.
- walk
- Directory spelunking
- BatchWriter
- Manages uncommitted writes
- BeginWriteValue
- The start of a write, before an exclusive file has been allocated. This allows for bringing your
own file, such as by rename, or file clone.
- Dir
- FileValues
- A value holding a statement temporary for starting an iterator over the Values of a value file.
I couldn’t seem to get the code to work without this.
- Handle
- Provides access to a storage directory. Manages manifest access, file cloning, file writers,
configuration, value eviction etc.
- NonzeroValueLocation
- Storage location info for a non-zero-length value.
- ReadTransactionOwned
- Helper type for wrapping rusqlite::Transaction to only provide ReadTransaction capabilities.
- Snapshot
- SnapshotValue
- Timestamp
- Transaction
- Value
- ValueWriter
- WriteCommitResult
- Error
- ValueLocation
- Location data for a value. Includes the case where the value is empty and so doesn’t require
allocation.
- LAST_USED_RESOLUTION
- MANIFEST_DB_FILE_NAME
- FileAlreadyExistsError
- ReadOnlyTransactionAccessor
- Exposes a rusqlite Transaction to implement ReadTransaction.
- ReadTransaction
- Extra methods for types exposing a rusqlite Transaction that’s allowed to do read transaction
stuff.
- ceil_multiple
- Divides value by multiple, always rounding up. Very common operation for allocators.
- check_hole
- Checks that there’s no data allocated in the region provided.
- PubResult
- Type to be exposed eventually from the lib instead of anyhow. Should be useful for the C API.
- ReadTransactionRef
- TimestampInner
