Return status codes.

Variants

FailedCannotMakeProgress = -4

More input data was expected, but the caller indicated that there was no more data, so the input stream is likely truncated.

This can’t happen if you have provided the TINFL_FLAG_HAS_MORE_INPUT flag to the decompression. By setting that flag, you indicate more input exists but is not provided, and so reaching the end of the input data without finding the end of the compressed stream would instead return a NeedsMoreInput status.

BadParam = -3

The output buffer is an invalid size; consider the flags parameter.

Adler32Mismatch = -2

The decompression went fine, but the adler32 checksum did not match the one provided in the header.

Failed = -1

Failed to decompress due to invalid data.

Done = 0

Finished decompression without issues.

This indicates the end of the compressed stream has been reached.

NeedsMoreInput = 1

The decompressor needs more input data to continue decompressing.

This occurs when there’s no more consumable input, but the end of the stream hasn’t been reached, and you have supplied the TINFL_FLAG_HAS_MORE_INPUT flag to the decompressor. Had you not supplied that flag (which would mean you were asserting that you believed all the data was available) you would have gotten a FailedCannotMakeProcess instead.

HasMoreOutput = 2

There is still pending data that didn’t fit in the output buffer.

Implementations

impl TINFLStatus

pub fn from_i32(value: i32) -> Option<TINFLStatus>

Trait Implementations

impl Clone for TINFLStatus

fn clone(&self) -> TINFLStatus

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TINFLStatus

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Hash for TINFLStatus

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for TINFLStatus

fn eq(&self, other: &TINFLStatus) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
