Enum Encoding 

pub enum Encoding {
    Uncompressed = 0,
    Internal = 1,
    Gzip = 2,
    Zlib = 4,
    Brotli = 8,
    Zstd = 16,
}

Variants

Uncompressed = 0

Data is not compressed, but it can be

Internal = 1

Some formats like JPEG and PNG are already compressed

Gzip = 2

Zlib = 4

Brotli = 8

Zstd = 16

Implementations

impl Encoding

pub fn parse(value: &str) -> Option<Self>

Parse the encoding from common names if they match

pub fn compression(self) -> Option<&'static str>

Returns None for Encoding::Uncompressed and Encoding::Internal: absence of the compression key in the metadata table means no external encoding.

pub fn is_encoded(self) -> bool

Trait Implementations

impl Clone for Encoding

fn clone(&self) -> Encoding

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Encoding

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

Formats the value using the given formatter.

impl Hash for Encoding

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Encoding

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