Module zebra_state::service::finalized_state::disk_format

Serialization formats for finalized data.

Correctness

crate::constants::state_database_format_version_in_code() must be incremented each time the database format (column, serialization, etc) changes.

Structs

• RawBytes
  Access database keys or values as raw bytes. Mainly for use in tests, runtime checks, or format compatibility code.

Traits

• FromDisk
  Helper type for reading types from disk as raw bytes.
• IntoDisk
  Helper type for writing types to disk as raw bytes. Also used to convert key types to raw bytes for disk lookups.

Functions

• expand_zero_be_bytes
  Expands disk_bytes to mem_len, by adding zero bytes at the start of the slice. Used to zero-fill bytes that were discarded during serialization.
• truncate_zero_be_bytes
  Truncates mem_bytes to disk_len, by removing zero bytes from the start of the slice. Used to discard unused zero bytes during serialization.
