|
||||
A potentially non-blocking response decoder.
|
||||
|
||||
The decoder wraps a stream of chunks and produces a new stream of decompressed chunks.
|
||||
The decompressed chunks aren't guaranteed to align to the compressed ones.
|
||||
|
||||
If the response is plaintext then no additional work is carried out.
|
||||
Chunks are just passed along.
|
||||
|
||||
If the response is gzip, then the chunks are decompressed into a buffer.
|
||||
Slices of that buffer are emitted as new chunks.
|
||||
|
||||
This module consists of a few main types:
|
||||
|
||||
- `ReadableChunks` is a `Read`-like wrapper around a stream
|
||||
- `Decoder` is a layer over `ReadableChunks` that applies the right decompression
|
||||
|
||||
The following types directly support the gzip compression case:
|
||||
|
||||
- `Pending` is a non-blocking constructor for a `Decoder` in case the body needs to be checked for EOF
|
||||
- `Peeked` is a buffer that keeps a few bytes available so `libflate`s `read_exact` calls won't fail
