Struct ChunkEntry 

pub struct ChunkEntry {
    pub row_offset: u64,
    pub num_rows: u32,
    pub byte_offset: u64,
    pub compressed_size: u32,
    pub uncompressed_size: u32,
}

Entry in the chunk index describing one chunk’s location

Fields

row_offset: u64

Row offset (first row in this chunk)

num_rows: u32

Number of rows in this chunk

byte_offset: u64

Byte offset in the payload section

compressed_size: u32

Compressed size in bytes

uncompressed_size: u32

Uncompressed size in bytes

Implementations

impl ChunkEntry

pub fn new( row_offset: u64, num_rows: u32, byte_offset: u64, compressed_size: u32, uncompressed_size: u32, ) -> Self

Create a new chunk entry

pub fn contains_row(&self, row: u64) -> bool

Check if this chunk contains the given row

pub fn end_row(&self) -> u64

Get the last row index in this chunk (exclusive)

Trait Implementations

impl Clone for ChunkEntry

fn clone(&self) -> ChunkEntry

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ChunkEntry

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ChunkEntry

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ChunkEntry

fn eq(&self, other: &ChunkEntry) -> 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 ChunkEntry

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 ChunkEntry
