Struct autocompress::io::ProcessorReader

pub struct ProcessorReader<P: Processor, R: BufRead> { /* private fields */ }

This struct that allows reading of data processed by a Processor from a BufRead.

Type Parameters

• P: The type of the Processor that processes the data.
• R: The type of the BufRead that provides the data.

Example

use autocompress::io::ProcessorReader;
use autocompress::zstd::ZstdDecompress;

let buf_reader = BufReader::new(File::open("testfiles/pg2701.txt.zst")?);
let mut zstd_reader = ProcessorReader::<ZstdDecompress, _>::new(buf_reader);
let mut buf = Vec::new();
zstd_reader.read_to_end(&mut buf)?;

Implementations

impl<P: Processor + Default, R: BufRead> ProcessorReader<P, R>

pub fn new(reader: R) -> Self

Create a new ProcessorReader from BufRead

impl<P: Processor, R: BufRead> ProcessorReader<P, R>

pub fn with_processor(processor: P, reader: R) -> Self

Create a new ProcessorReader with specified Processor.

Example

use autocompress::io::ProcessorReader;
use autocompress::zstd::ZstdDecompress;

let buf_reader = BufReader::new(File::open("testfiles/pg2701.txt.zst")?);
let zstd_decompress = ZstdDecompress::new()?;
let mut zstd_reader = ProcessorReader::with_processor(zstd_decompress, buf_reader);
let mut buf = Vec::new();
zstd_reader.read_to_end(&mut buf)?;

pub fn into_inner_reader(self) -> R

Unwraps this ProcessorReader<P, R>, returning the underlying reader.

Trait Implementations

impl<P: Processor, R: BufRead> Read for ProcessorReader<P, R>

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.
