Expand description

A struct that compbines a decompressor with extra data for streaming decompression.

Fields§

§decomp: DecompressorOxide

Inner decompressor struct

§dict: [u8; 32768]

Buffer of input bytes for matches. TODO: Could probably do this a bit cleaner with some Cursor-like class. We may also look into whether we need to keep a buffer here, or just one in the decompressor struct.

§dict_ofs: usize

Where in the buffer are we currently at?

§dict_avail: usize

How many bytes of data to be flushed is there currently in the buffer?

§first_call: bool§has_flushed: bool§data_format: DataFormat

Whether the input data is wrapped in a zlib header and checksum. TODO: This should be stored in the decompressor.

§last_status: TINFLStatus

Implementations§

source§

impl InflateState

source

pub fn new(data_format: DataFormat) -> InflateState

Create a new state.

Note that this struct is quite large due to internal buffers, and as such storing it on the stack is not recommended.

§Parameters

data_format: Determines whether the compressed data is assumed to wrapped with zlib metadata.

source

pub fn new_boxed(data_format: DataFormat) -> Box<InflateState>

Create a new state on the heap.

§Parameters

data_format: Determines whether the compressed data is assumed to wrapped with zlib metadata.

source

pub fn decompressor(&mut self) -> &mut DecompressorOxide

Access the innner decompressor.

source

pub const fn last_status(&self) -> TINFLStatus

Return the status of the last call to inflate with this InflateState.

source

pub fn new_boxed_with_window_bits(window_bits: i32) -> Box<InflateState>

Create a new state using miniz/zlib style window bits parameter.

The decompressor does not support different window sizes. As such, any positive (>0) value will set the zlib header flag, while a negative one will not.

source

pub fn reset(&mut self, data_format: DataFormat)

Reset the decompressor without re-allocating memory, using the given data format.

source

pub fn reset_as<T: ResetPolicy>(&mut self, policy: T)

Resets the state according to specified policy.
