Struct BlockMetadata 

pub struct BlockMetadata { /* private fields */ }

Read-only metadata for one complete, committed data block.

Implementations

impl BlockMetadata

pub fn sequence(&self) -> u64

The contiguous data-frame sequence number, beginning at one.

pub fn file_offset(&self) -> u64

The absolute byte offset of this frame’s prefix.

pub fn total_length(&self) -> u64

The complete committed frame length, including prefix and trailer.

pub fn row_count(&self) -> u64

The logical row count declared by the block.

pub fn base_row_id(&self) -> Option<u64>

The base row ID when the file’s ROW_IDS feature is enabled.

pub fn primary_bounds(&self) -> Option<PrimaryBounds>

The block’s primary timestamp/date bounds, if the schema has a primary.

pub fn ts_sorted(&self) -> bool

Whether this block declares nondecreasing primary values.

The claim covers this block’s primary timestamp column only. It says nothing about ordering between blocks or about any other column, and a metadata-only open does not verify it against the stored values.
