Struct RunLengthEncoder

pub struct RunLengthEncoder;

Expand description

Run-Length Encoding implementation

Implementations§

impl RunLengthEncoder

pub fn encode(data: &[u8]) -> Result<Vec<u8>>

Encode data using run-length encoding

pub fn decode(encoded: &[u8]) -> Result<Vec<u8>>

Decode run-length encoded data

pub fn encode_u64(values: &[u64]) -> Vec<u8> ⓘ

Encode a u64 sequence using run-length encoding.

Consecutive equal values are grouped into runs of (value: u64 LE, count: u32 LE) = 12 bytes.

pub fn decode_u64(data: &[u8]) -> Result<Vec<u64>>

Decode a u64 run-length encoded byte sequence produced by encode_u64.

pub fn estimate_compression_ratio(data: &[u8]) -> f64

Estimate compression ratio for given data

Trait Implementations§

impl CompressionAlgorithm for RunLengthEncoder

fn compress(&self, data: &[u8]) -> Result<CompressedData>

Compress data and return compressed bytes with metadata

fn decompress(&self, compressed: &CompressedData) -> Result<Vec<u8>>

Decompress data

fn algorithm_type(&self) -> AdvancedCompressionType

Get algorithm type

Blanket Implementations§

impl<T> Any for T
where T: 'static + ?Sized,

fn type_id(&self) -> TypeId

Gets the TypeId of self. Read more

impl<T> Borrow<T> for T
where T: ?Sized,

fn borrow(&self) -> &T

Immutably borrows from an owned value. Read more

impl<T> BorrowMut<T> for T
where T: ?Sized,

fn borrow_mut(&mut self) -> &mut T

Mutably borrows from an owned value. Read more

impl<ST, DT> CastableFrom<ST, Initialized, Initialized> for DT
where ST: ?Sized, DT: ?Sized,

impl<ST, DT> CastableFrom<ST, Uninit, Uninit> for DT
where ST: ?Sized, DT: ?Sized,

impl<T> Downcast for T
where T: Any,

fn into_any(self: Box<T>) -> Box<dyn Any>

Converts Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>, which can then be downcast into Box<dyn ConcreteType> where ConcreteType implements Trait.

fn into_any_rc(self: Rc<T>) -> Rc<dyn Any>

Converts Rc<Trait> (where Trait: Downcast) to Rc<Any>, which can then be further downcast into Rc<ConcreteType> where ConcreteType implements Trait.

fn as_any(&self) -> &(dyn Any + 'static)

Converts &Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &Any’s vtable from &Trait’s.

fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)

Converts &mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &mut Any’s vtable from &mut Trait’s.

where T: Any + Send,

fn into_any_send(self: Box<T>) -> Box<dyn Any + Send>

Converts Box<Trait> (where Trait: DowncastSend) to Box<dyn Any + Send>, which can then be downcast into Box<ConcreteType> where ConcreteType implements Trait.

impl<T> DowncastSync for T
where T: Any + Send + Sync,

fn into_any_sync(self: Box<T>) -> Box<dyn Any + Sync + Send>

Converts Box<Trait> (where Trait: DowncastSync) to Box<dyn Any + Send + Sync>, which can then be downcast into Box<ConcreteType> where ConcreteType implements Trait.

fn into_any_arc(self: Arc<T>) -> Arc<dyn Any + Sync + Send> ⓘ

Converts Arc<Trait> (where Trait: DowncastSync) to Arc<Any>, which can then be downcast into Arc<ConcreteType> where ConcreteType implements Trait.
