Struct Block 

pub struct Block {
    pub coders: Vec<Coder>,
    pub has_crc: bool,
    pub crc: u64,
    /* private fields */
}

Represents a compression block.

A block contains one or more coders (compression/filter methods) that are chained together to process data.

Fields

coders: Vec<Coder>

Coders (compression/filter methods) in this block.

has_crc: bool

Whether this block has a CRC checksum.

crc: u64

CRC32 checksum of the block data.

Implementations

impl Block

pub fn get_unpack_size(&self) -> u64

Returns the total uncompressed size of data in this block.

pub fn get_unpack_size_for_coder(&self, coder: &Coder) -> u64

Returns the uncompressed size for a specific coder within this block.

Arguments

• coder - The coder to get the unpack size for

pub fn get_unpack_size_at_index(&self, index: usize) -> u64

Returns the uncompressed size for the coder at the specified index.

Arguments

• index - The index of the coder to get the unpack size for

pub fn ordered_coder_iter(&self) -> OrderedCoderIter<'_>

Returns an iterator over the coders in their processing order.

Coders are chained together in blocks, and this iterator follows the chain from the first coder to the last in their proper execution order.

Trait Implementations

impl Clone for Block

fn clone(&self) -> Block

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Block

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

Formats the value using the given formatter.

impl Default for Block

fn default() -> Block

Returns the “default value” for a type.
