Struct ChunkHeader

pub struct ChunkHeader {
    pub chunk_type: ChunkType,
    pub chunk_size: u32,
    pub total_size: u32,
}

Header of a chunk

Fields

chunk_type: ChunkType

The type of the chunk

chunk_size: u32

Output size of the chunk in blocksize

total_size: u32

Size of the chunk in the sparse image

Implementations

impl ChunkHeader

pub fn new_dontcare(blocks: u32) -> Self

Create a don’t care header for a given length in blocks

pub fn new_raw(blocks: u32, block_size: u32) -> Self

Create a new raw header for a given amount in blocks for block_size

The actual data should follow this header

pub fn new_fill(blocks: u32) -> Self

Create a new fill header for a given amount of blocks to be filled

The header should be followed by 4 bytes indicate the data to fill with

pub fn from_bytes(bytes: &ChunkHeaderBytes) -> Result<ChunkHeader, ParseError>

Create new ChunkHeader from a raw header

pub fn to_bytes(&self) -> ChunkHeaderBytes

Convert into a raw header

pub fn out_size(&self, header: &FileHeader) -> usize

Resulting size of this chunk in the output

pub fn data_size(&self) -> usize

Data bytes after the header

Trait Implementations

impl Clone for ChunkHeader

fn clone(&self) -> ChunkHeader

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ChunkHeader

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

Formats the value using the given formatter.

impl PartialEq for ChunkHeader

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