Enum Compression 

#[repr(u8)]
pub enum Compression {
    Unknown = 0,
    None = 1,
    Gzip = 2,
    Brotli = 3,
    Zstd = 4,
}

Compression algorithm for PMTiles.

Values match the PMTiles v3 spec:

• 0: Unknown
• 1: None
• 2: Gzip
• 3: Brotli
• 4: Zstd

Variants

Unknown = 0

None = 1

Gzip = 2

Brotli = 3

Zstd = 4

Implementations

impl Compression

pub fn from_str(s: &str) -> Option<Self>

Parse compression from string (case-insensitive).

Valid values: “none”, “gzip”, “brotli”, “zstd”

pub fn code(&self) -> u8

Get the PMTiles byte code for this compression type.

pub fn from_code(code: u8) -> Option<Self>

Parse a PMTiles spec byte code back into a compression type.

Inverse of Compression::code. Returns None for codes outside the PMTiles v3 spec (0-4).

pub fn name(&self) -> &'static str

Get a human-readable name for this compression type.

Trait Implementations

impl Copy for Compression

impl Debug for Compression

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

Formats the value using the given formatter.

impl Default for Compression

fn default() -> Compression

Returns the “default value” for a type.

impl Eq for Compression
