Struct CompressionRegistry 

pub struct CompressionRegistry { /* private fields */ }

Registry that tracks which compression algorithms are available at runtime and which one is the default.

Implementations

impl CompressionRegistry

pub fn new() -> Self

Create a new registry with all feature-enabled algorithms and None as the default.

pub fn with_default(algo: CompressionType) -> Result<Self, String>

Create a registry with a specific default algorithm.

The available list is still populated from enabled features. Returns an error string if algo is not in the available set.

pub fn default_type(&self) -> CompressionType

The default compression type.

pub fn available_types(&self) -> &[CompressionType]

All compression types currently available.

pub fn is_available(&self, algo: &CompressionType) -> bool

Check whether a given compression type is available.
