impl DecoderBuffer
pub fn new() -> Self
Sourcepub unsafe fn from_buffer_ptr(data_ptr: *const c_char, size: usize) -> Self
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
Sourcepub fn from_buffer(data_buffer: &[u8]) -> Self
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
Sourcepub fn from_encoder_buffer(encoder_buffer: &mut EncoderBuffer) -> Self
pub fn from_encoder_buffer(encoder_buffer: &mut EncoderBuffer) -> Self
Initializes the decoder buffer with the data from the encoder buffer
