Struct ExtensibleArrayDataBlock 

pub struct ExtensibleArrayDataBlock {
    pub class_id: u8,
    pub header_addr: u64,
    pub block_offset: u64,
    pub elements: Vec<u64>,
}

Extensible array data block.

On-disk layout:

"EADB"(4) + version=0(1) + class_id(1)
+ header_addr(sizeof_addr)
+ block_offset (variable length)
+ elements(nelmts * raw_elmt_size)
+ checksum(4)

Fields

class_id: u8

header_addr: u64

block_offset: u64

elements: Vec<u64>

Chunk addresses.

Implementations

impl ExtensibleArrayDataBlock

pub fn new(header_addr: u64, block_offset: u64, nelmts: usize) -> Self

Create a new empty data block.

pub fn block_offset_size(max_nelmts_bits: u8) -> usize

Number of bytes needed for the block_offset field.

pub fn encoded_size(&self, ctx: &FormatContext, max_nelmts_bits: u8) -> usize

Compute the encoded size.

pub fn encode(&self, ctx: &FormatContext, max_nelmts_bits: u8) -> Vec<u8>

pub fn decode( buf: &[u8], ctx: &FormatContext, max_nelmts_bits: u8, nelmts: usize, ) -> FormatResult<Self>

Trait Implementations

impl Clone for ExtensibleArrayDataBlock

fn clone(&self) -> ExtensibleArrayDataBlock

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ExtensibleArrayDataBlock

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

Formats the value using the given formatter.

impl PartialEq for ExtensibleArrayDataBlock

fn eq(&self, other: &ExtensibleArrayDataBlock) -> 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.
