Struct CompressionHeader 

pub struct CompressionHeader {
    pub ch_type: u32,
    pub ch_size: u64,
    pub ch_addralign: u64,
}

A unified CompressionHeader - convertable to and from 32-bit and 64-bit variants

Fields

ch_type: u32

Compression format

ch_size: u64

Uncompressed data size

ch_addralign: u64

Uncompressed data alignment

Implementations

impl CompressionHeader

pub fn size(ctx: Ctx) -> usize

Return the size of the underlying compression header, given a container

pub fn new() -> Self

pub fn parse(bytes: &[u8], offset: usize, ctx: Ctx) -> Result<CompressionHeader>

Parse a compression header from bytes at offset, using the given ctx

Trait Implementations

impl Clone for CompressionHeader

fn clone(&self) -> CompressionHeader

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CompressionHeader

Available on crate feature alloc only.

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

Formats the value using the given formatter.

impl Default for CompressionHeader

fn default() -> CompressionHeader

Returns the “default value” for a type.

impl From<CompressionHeader> for ElfCompressionHeader

Available on crate feature alloc only.

fn from(ch: CompressionHeader) -> Self

Converts to this type from the input type.

impl From<CompressionHeader> for CompressionHeader

Available on crate feature alloc only.

fn from(ch: ElfCompressionHeader) -> Self

Converts to this type from the input type.

impl From<CompressionHeader> for ElfCompressionHeader

Available on crate feature alloc only.

impl IntoCtx<Ctx> for CompressionHeader

Available on crate feature alloc only.

fn into_ctx(self, bytes: &mut [u8], _: Ctx)

impl PartialEq for CompressionHeader

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