Struct ReftableReader 

pub struct ReftableReader { /* private fields */ }

Reads a single reftable file from a byte buffer.

Implementations

impl ReftableReader

pub fn new(data: Vec<u8>) -> Result<Self>

Open a reftable from bytes.

pub fn from_arc(data: Arc<[u8]>) -> Result<Self>

Open a reftable from shared bytes (avoids cloning table payloads).

pub fn read_refs(&self) -> Result<Vec<RefRecord>>

Read all ref records from the table.

pub fn for_each_ref( &self, f: impl FnMut(&RefRecord) -> ControlFlow<()>, ) -> Result<()>

Visit ref records in sorted name order, optionally bounded by lower (inclusive) and upper_exclusive (exclusive). When upper_exclusive is None, iteration continues through the last ref block.

pub fn for_each_ref_in_range( &self, lower: &str, upper_exclusive: Option<&str>, f: impl FnMut(&RefRecord) -> ControlFlow<()>, ) -> Result<()>

Visit ref records with name >= lower and < upper_exclusive when set.

pub fn lookup_ref(&self, name: &str) -> Result<Option<RefRecord>>

Look up a single ref by name.

pub fn read_logs(&self) -> Result<Vec<LogRecord>>

Read all log records from the table.

pub fn block_size(&self) -> u32

Get the block size from the header.

pub fn min_update_index(&self) -> u64

Get the min update index.

pub fn max_update_index(&self) -> u64

Get the max update index.

pub fn ref_index_offset(&self) -> u64

Byte offset of the top-level ref index section, or 0 if none.

pub fn payload_size(&self) -> u64

Effective ref payload size for compaction heuristics (file size minus header overhead).
