Struct lz4_java_wrc::Lz4BlockInputBase

pub struct Lz4BlockInputBase<R: Read + Sized, C: Compression> { /* private fields */ }

Wrapper around a Read object to decompress data.

Use this struct only if you want to provide your own Compression implementation. Otherwise use the alias Lz4BlockInput.

Implementations

impl<R: Read> Lz4BlockInputBase<R, Context>

pub fn new(r: R) -> Self

Create a new Lz4BlockInput with the default Compression implementation.

See Self::with_context()

impl<R: Read, C: Compression> Lz4BlockInputBase<R, C>

pub fn with_context(r: R, c: C) -> Self

Create a new Lz4BlockInputBase with the default checksum implementation which matches the Java’s default implementation, including the missing 4 bits bug.

See Self::with_checksum()

pub fn with_checksum( r: R, c: C, checksum: fn(_: &[u8]) -> u32, stop_on_empty_block: bool ) -> Self

Create a new Lz4BlockInputBase.

The checksum must return a u32.

Trait Implementations

impl<R: Debug + Read + Sized, C: Debug + Compression> Debug for Lz4BlockInputBase<R, C>

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

Formats the value using the given formatter.

impl<R: Read, C: Compression> Read for Lz4BlockInputBase<R, C>

fn read(&mut self, buf: &mut [u8]) -> Result<usize>

Pull some bytes from this source into the specified buffer, returning how many bytes were read.

fn read_vectored(&mut self, bufs: &mut [IoSliceMut<'_>]) -> Result<usize, Error>

Like read, except that it reads into a slice of buffers.

fn is_read_vectored(&self) -> bool

🔬This is a nightly-only experimental API. (can_vector)

Determines if this Reader has an efficient read_vectored implementation.

fn read_to_end(&mut self, buf: &mut Vec<u8>) -> Result<usize, Error>

Read all bytes until EOF in this source, placing them into buf.

fn read_to_string(&mut self, buf: &mut String) -> Result<usize, Error>

Read all bytes until EOF in this source, appending them to buf.

fn read_exact(&mut self, buf: &mut [u8]) -> Result<(), Error>

Read the exact number of bytes required to fill buf.

fn read_buf(&mut self, buf: BorrowedCursor<'_>) -> Result<(), Error>

🔬This is a nightly-only experimental API. (read_buf)

Pull some bytes from this source into the specified buffer.

fn read_buf_exact(&mut self, cursor: BorrowedCursor<'_>) -> Result<(), Error>

🔬This is a nightly-only experimental API. (read_buf)

Read the exact number of bytes required to fill cursor.

fn by_ref(&mut self) -> &mut Self

where Self: Sized,

Creates a “by reference” adaptor for this instance of Read.

fn bytes(self) -> Bytes<Self>

where Self: Sized,

Transforms this Read instance to an Iterator over its bytes.

fn chain<R>(self, next: R) -> Chain<Self, R>

where R: Read, Self: Sized,

Creates an adapter which will chain this stream with another.

fn take(self, limit: u64) -> Take<Self>

where Self: Sized,

Creates an adapter which will read at most limit bytes from it.
