Crate possum

Modules

• env
• sys
  Exposes required lower-level OS primitives for sparse files, block cloning, and file locking.
• walk
  Directory spelunking

Structs

• 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.
• ReadTransaction
  Only provides methods that are known to be read only, and has a ReadOnly connection internally.
• Reader
• Snapshot
• SnapshotValue
• Timestamp
• Value
• ValueWriter
• WriteCommitResult

Enums

• Error
• ValueLocation
  Location data for a value. Includes the case where the value is empty and so doesn’t require allocation.

Constants

• LAST_USED_RESOLUTION
• MANIFEST_DB_FILE_NAME

Traits

• FileAlreadyExistsError

Functions

• 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.

Type Aliases

• PubResult
  Type to be exposed eventually from the lib instead of anyhow. Should be useful for the C API.
• ReadTransactionOwned
• ReadTransactionRef
• TimestampInner
