Struct ContentCompression 

pub struct ContentCompression {
    pub crc32: Option<Crc32>,
    pub void: Option<Void>,
    pub content_comp_algo: ContentCompAlgo,
    pub content_comp_settings: Option<ContentCompSettings>,
}

Settings describing the compression used. This Element MUST be present if the value of ContentEncodingType is 0 and absent otherwise. Each block MUST be decompressable even if no previous block is available in order not to prevent seeking.

Fields

crc32: Option<Crc32>

Optional CRC-32 element for integrity checking.

void: Option<Void>

void element, useful for reserving space during writing.

content_comp_algo: ContentCompAlgo

The compression algorithm used. Compression method “1” (bzlib) and “2” (lzo1x) are lacking proper documentation on the format which limits implementation possibilities. Due to licensing conflicts on commonly available libraries compression methods “2” (lzo1x) does not offer widespread interoperability. A Matroska Writer SHOULD NOT use these compression methods by default. A Matroska Reader MAY support methods “1” and “2” as possible, and SHOULD support other methods.

• 0 - zlib,
• 1 - bzlib,
• 2 - lzo1x,
• 3 - Header Stripping

content_comp_settings: Option<ContentCompSettings>

Settings that might be needed by the decompressor. For Header Stripping (ContentCompAlgo=3), the bytes that were removed from the beginning of each frames of the track.

Trait Implementations

impl Clone for ContentCompression

fn clone(&self) -> ContentCompression

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ContentCompression

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

Formats the value using the given formatter.

impl Default for ContentCompression

fn default() -> ContentCompression

Returns the “default value” for a type.

impl Element for ContentCompression

const ID: VInt64

EBML ID of the element.

fn decode_body(buf: &mut &[u8]) -> Result<Self>

Decode the body of the element from a buffer.

fn encode_body<B: BufMut>(&self, buf: &mut B) -> Result<()>

Encode the body of the element to a buffer.

const HAS_DEFAULT_VALUE: bool = false

Whether the element has a default value, as per Matroska specification. If true, and the element is missing in a master element, it should be treated as if it were present with the default value. If false, and the element is missing in a master element, it should be treated as an error.

impl PartialEq for ContentCompression

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