Implementations

impl BlobMetadata

pub fn blob_type(&self) -> &str

See blob types: https://iceberg.apache.org/puffin-spec/#blob-types

pub fn fields(&self) -> &[i32]

List of field IDs the blob was computed for; the order of items is used to compute sketches stored in the blob.

pub fn snapshot_id(&self) -> i64

ID of the Iceberg table’s snapshot the blob was computed from

pub fn sequence_number(&self) -> i64

Sequence number of the Iceberg table’s snapshot the blob was computed from

pub fn offset(&self) -> u64

The offset in the file where the blob contents start

pub fn length(&self) -> u64

The length of the blob stored in the file (after compression, if compressed)

pub fn compression_codec(&self) -> CompressionCodec

The compression codec used to compress the data

pub fn properties(&self) -> &HashMap<String, String>

Arbitrary meta-information about the blob

Trait Implementations

impl Clone for BlobMetadata

fn clone(&self) -> BlobMetadata

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for BlobMetadata

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for BlobMetadata

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for BlobMetadata

fn eq(&self, other: &BlobMetadata) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for BlobMetadata

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for BlobMetadata
