Struct flate2::ffi::rust::inflate::stream::InflateState

pub struct InflateState {
    decomp: DecompressorOxide,
    dict: [u8; 32768],
    dict_ofs: usize,
    dict_avail: usize,
    first_call: bool,
    has_flushed: bool,
    data_format: DataFormat,
    last_status: TINFLStatus,
}

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

Fields

decomp: DecompressorOxide

dict: [u8; 32768]

dict_ofs: usize

dict_avail: usize

first_call: bool

has_flushed: bool

data_format: DataFormat

last_status: TINFLStatus

Implementations

impl InflateState

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.

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.

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

Access the innner decompressor.

pub const fn last_status(&self) -> TINFLStatus

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

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.

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

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

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

where T: ResetPolicy,

Resets the state according to specified policy.

Trait Implementations

impl Clone for InflateState

fn clone(&self) -> InflateState

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Default for InflateState

fn default() -> InflateState

Returns the “default value” for a type.
