Struct ContentEncoding 

pub struct ContentEncoding {
    pub crc32: Option<Crc32>,
    pub void: Option<Void>,
    pub content_encoding_order: ContentEncodingOrder,
    pub content_encoding_scope: ContentEncodingScope,
    pub content_encoding_type: ContentEncodingType,
    pub content_compression: Option<ContentCompression>,
    pub content_encryption: Option<ContentEncryption>,
}

Settings for one content encoding like compression or encryption.

Fields

crc32: Option<Crc32>

Optional CRC-32 element for integrity checking.

void: Option<Void>

void element, useful for reserving space during writing.

content_encoding_order: ContentEncodingOrder

Tell in which order to apply each ContentEncoding of the ContentEncodings. The decoder/demuxer MUST start with the ContentEncoding with the highest ContentEncodingOrder and work its way down to the ContentEncoding with the lowest ContentEncodingOrder. This value MUST be unique over for each ContentEncoding found in the ContentEncodings of this TrackEntry.

content_encoding_scope: ContentEncodingScope

A bit field that describes which Elements have been modified in this way. Values (big-endian) can be OR’ed.

• 1 - Block,
• 2 - Private,
• 4 - Next

content_encoding_type: ContentEncodingType

A value describing what kind of transformation is applied.

• 0 - Compression,
• 1 - Encryption

content_compression: Option<ContentCompression>

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.

content_encryption: Option<ContentEncryption>

Settings describing the encryption used. This Element MUST be present if the value of ContentEncodingType is 1 (encryption) and MUST be ignored otherwise. A Matroska Player MAY support encryption.

Trait Implementations

impl Clone for ContentEncoding

fn clone(&self) -> ContentEncoding

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ContentEncoding

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

Formats the value using the given formatter.

impl Default for ContentEncoding

fn default() -> ContentEncoding

Returns the “default value” for a type.

impl Element for ContentEncoding

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 ContentEncoding

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