Enum Method 

pub enum Method {
    None,
    Aes128,
    SampleAes,
    SampleAesCtr,
}

Corresponds to the #EXT-X-KEY:METHOD attribute.

See Key for a link to the HLS documentation for this attribute.

Variants

None

Media Segments are not encrypted.

Aes128

Media Segments are completely encrypted using the Advanced Encryption Standard (AES) with a 128-bit key, Cipher Block Chaining (CBC), and Public-Key Cryptography Standards #7 (PKCS7) padding [RFC5652]. CBC is restarted on each segment boundary, using either the Initialization Vector (IV) attribute value or the Media Sequence Number as the IV.

SampleAes

the Media Segments are Sample Encrypted using the Advanced Encryption Standard. How these media streams are encrypted and encapsulated in a segment depends on the media encoding and the media format of the segment. fMP4 Media Segments are encrypted using the ‘cbcs’ scheme of Common Encryption. Encryption of other Media Segment formats containing H.264, AAC, AC-3, and Enhanced AC-3 media streams is described in the HTTP Live Streaming (HLS) Sample Encryption specification.

SampleAesCtr

An encryption method of SAMPLE-AES-CTR is similar to SAMPLE-AES. However, fMP4 Media Segments are encrypted using the ‘cenc’ scheme of Common Encryption. Encryption of other Media Segment formats is not defined for SAMPLE-AES-CTR.

Trait Implementations

impl Clone for Method

fn clone(&self) -> Method

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Method

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

Formats the value using the given formatter.

impl Display for Method

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

Formats the value using the given formatter.

impl From<Method> for Cow<'_, str>

fn from(value: Method) -> Self

Converts to this type from the input type.

impl From<Method> for EnumeratedString<'_, Method>

fn from(value: Method) -> Self

Converts to this type from the input type.

impl PartialEq for Method

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

impl<'a> TryFrom<&'a str> for Method

type Error = UnrecognizedEnumerationError<'a>

The type returned in the event of a conversion error.

fn try_from(value: &'a str) -> Result<Self, Self::Error>

Performs the conversion.

impl Copy for Method
