Implementations§

Source§

impl DecoderBuffer

Source

pub fn new() -> Self

Source

pub unsafe fn from_buffer_ptr(data_ptr: *const c_char, size: usize) -> Self

Initializes the decoder buffer with a raw data pointer and size

§Safety

The data pointer must be valid for the lifetime of the decoder buffer

Source

pub fn from_buffer(data_buffer: &[u8]) -> Self

Initializes the decoder buffer with a slice of data

§Safety

The given slice must be valid for the lifetime of the decoder buffer

Source

pub fn from_encoder_buffer(encoder_buffer: &mut EncoderBuffer) -> Self

Initializes the decoder buffer with the data from the encoder buffer
