-/// Main decompression function. Keeps decompressing data from `in_buf` until the `in_buf` is
-/// empty, `out` is full, the end of the deflate stream is hit, or there is an error in the
-/// deflate stream.
-///
-/// # Arguments
-///
-/// `r` is a [`DecompressorOxide`] struct with the state of this stream.
-///
-/// `in_buf` is a reference to the compressed data that is to be decompressed. The decompressor will
-/// start at the first byte of this buffer.
-///
-/// `out` is a reference to the buffer that will store the decompressed data, and that
-/// stores previously decompressed data if any.
-///
-/// * The offset given by `out_pos` indicates where in the output buffer slice writing should start.
-/// * If [`TINFL_FLAG_USING_NON_WRAPPING_OUTPUT_BUF`] is not set, the output buffer is used in a
-/// wrapping manner, and it's size is required to be a power of 2.
-/// * The decompression function normally needs access to 32KiB of the previously decompressed data
-///(or to the beginning of the decompressed data if less than 32KiB has been decompressed.)
-///     - If this data is not available, decompression may fail.
-///     - Some deflate compressors allow specifying a window size which limits match distances to
-/// less than this, or alternatively an RLE mode where matches will only refer to the previous byte
-/// and thus allows a smaller output buffer. The window size can be specified in the zlib
-/// header structure, however, the header data should not be relied on to be correct.
-///
-/// `flags` indicates settings and status to the decompression function.
-/// * The [`TINFL_FLAG_HAS_MORE_INPUT`] has to be specified if more compressed data is to be provided
-/// in a subsequent call to this function.
-/// * See the the [`inflate_flags`] module for details on other flags.
-///
-/// # Returns
-///
-/// Returns a tuple containing the status of the compressor, the number of input bytes read, and the
-/// number of bytes output to `out`.
-///
-/// This function shouldn't panic pending any bugs.
