Struct deflate::write::GzEncoder [−][src]
pub struct GzEncoder<W: Write> { /* fields omitted */ }
Expand description
A Gzip encoder/compressor.
A struct implementing a Write
interface that takes arbitrary data and compresses it to
the provided writer using DEFLATE compression with Gzip headers and trailers.
Examples
use std::io::Write;
use deflate::Compression;
use deflate::write::GzEncoder;
let data = b"This is some test data";
let mut encoder = GzEncoder::new(Vec::new(), Compression::Default);
encoder.write_all(data)?;
let compressed_data = encoder.finish()?;
Implementations
Create a new GzEncoder
writing deflate-compressed data to the underlying writer when
written to, wrapped in a gzip header and trailer. The header details will be blank.
pub fn from_builder<O: Into<CompressionOptions>>(
builder: GzBuilder,
writer: W,
options: O
) -> GzEncoder<W>ⓘ
pub fn from_builder<O: Into<CompressionOptions>>(
builder: GzBuilder,
writer: W,
options: O
) -> GzEncoder<W>ⓘ
Create a new GzEncoder from the provided GzBuilder
. This allows customising
the details of the header, such as the filename and comment fields.
Encode all pending data to the contained writer, consume this GzEncoder
,
and return the contained writer if writing succeeds.
Resets the encoder (except the compression options), replacing the current writer with a new one, returning the old one. (Using a blank header).
Resets the encoder (except the compression options), replacing the current writer
with a new one, returning the old one, and using the provided GzBuilder
to
create the header.
Trait Implementations
Flush the encoder.
This will flush the encoder, emulating the Sync flush method from Zlib. This essentially finishes the current block, and sends an additional empty stored block to the writer.
