Struct FileMetadata 

pub struct FileMetadata { /* private fields */ }

File-level metadata retained by a Reader snapshot.

Implementations

impl FileMetadata

pub fn format_version(&self) -> (u16, u16)

The format version declared by the file prologue.

pub fn feature_flags(&self) -> u64

The prologue feature flags.

pub fn file_id(&self) -> &[u8; 16]

The opaque file ID from the prologue. It is identity metadata, not a content hash.

pub fn schema_id(&self) -> u64

The schema ID shared by the schema and data frames.

pub fn file_size(&self) -> u64

The file length observed when the reader opened it.

pub fn last_good_offset(&self) -> u64

The byte after the last complete committed frame.

pub fn block_count(&self) -> u64

The number of complete data blocks in this snapshot.

pub fn total_rows(&self) -> u64

The checked sum of the row counts of all complete data blocks.

pub fn incomplete_tail(&self) -> bool

Whether a final append ended before its next frame was committed.

False means the snapshot ends exactly after its last committed frame.
