Struct CompressionHeader 

#[repr(C)]
pub struct CompressionHeader {
    pub ch_type: u32,
    pub ch_reserved: u32,
    pub ch_size: u64,
    pub ch_addralign: u64,
}

Fields

ch_type: u32

Compression format

ch_reserved: u32

ch_size: u64

Uncompressed data size

ch_addralign: u64

Uncompressed data alignment

Implementations

impl CompressionHeader

pub fn from_bytes(bytes: &[u8]) -> CompressionHeader

pub fn from_fd(fd: &mut File, offset: u64) -> Result<CompressionHeader>

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 Copy for CompressionHeader

impl Debug for CompressionHeader

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 Eq for CompressionHeader

impl From<CompressionHeader> for CompressionHeader

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 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.
