Struct RecordInfo 

pub struct RecordInfo { /* private fields */ }

Record header, internal to FASTER.

The header is 8 bytes and contains:

• Previous address (48 bits): Points to the previous record in the hash chain
• Checkpoint version (13 bits): Version when record was created
• Invalid bit (1 bit): Whether the record has been invalidated
• Tombstone bit (1 bit): Whether this is a delete marker
• Final bit (1 bit): Whether this is the final record in a chain

Implementations

impl RecordInfo

pub fn new( previous_address: Address, checkpoint_version: u16, invalid: bool, tombstone: bool, final_bit: bool, ) -> Self

Create a new record info.

pub fn from_control(control: u64) -> Self

Create a record info from raw control value.

pub fn is_null(&self) -> bool

Check if the record info is null (all zeros).

pub fn previous_address(&self) -> Address

Get the previous address in the hash chain.

pub fn set_previous_address(&self, addr: Address)

Set the previous address.

pub fn checkpoint_version(&self) -> u16

Get the checkpoint version.

pub fn is_invalid(&self) -> bool

Check if the record is invalid.

pub fn set_invalid(&self, invalid: bool)

Set the invalid flag.

pub fn is_tombstone(&self) -> bool

Check if this is a tombstone (delete marker).

pub fn set_tombstone(&self, tombstone: bool)

Set the tombstone flag.

pub fn is_final(&self) -> bool

Check if this is the final record in a chain.

pub fn in_read_cache(&self) -> bool

pub fn control(&self) -> u64

Get the raw control value.

pub fn load(&self, ordering: Ordering) -> u64
