Struct BuffReader 

pub struct BuffReader<'a> {
    pub position: usize,
    /* private fields */
}

Buff reader is reading corresponding types from buffer (Byte array) and stores current position (later as cursor) In case of failure, the BuffReader remains in the same state as before the method call.

Fields

position: usize

Implementations

impl<'a> BuffReader<'a>

pub fn increment_position(&mut self, increment: usize)

pub fn new(buffer: &'a [u8], buff_len: usize) -> Self

pub fn read_variable_byte_int(&mut self) -> Result<u32, BufferError>

Variable byte integer can be 1-4 Bytes long. Buffer reader takes all 4 Bytes at first and than check what is true length of varbyteint and increment cursor by that

pub fn read_u32(&mut self) -> Result<u32, BufferError>

Reading u32 from buffer as Big endian

pub fn read_u16(&mut self) -> Result<u16, BufferError>

Reading u16 from buffer as Big endinan

pub fn read_u8(&mut self) -> Result<u8, BufferError>

Reading one byte from buffer as Big endian

pub fn read_string(&mut self) -> Result<EncodedString<'a>, BufferError>

Reading UTF-8 encoded string from buffer

pub fn read_binary(&mut self) -> Result<BinaryData<'a>, BufferError>

Read Binary data from buffer

pub fn read_string_pair(&mut self) -> Result<StringPair<'a>, BufferError>

Read string pair from buffer

pub fn read_message(&mut self, total_len: usize) -> &'a [u8]

Read payload message from buffer

pub fn peek_u8(&self) -> Result<u8, BufferError>

Peeking (without incremental internal pointer) one byte from buffer as Big endian
