Struct BufferReader 

pub struct BufferReader<'a> { /* private fields */ }

Lese-Buffer mit Alignment-Tracking.

Implementations

impl<'a> BufferReader<'a>

pub fn new(bytes: &'a [u8], endianness: Endianness) -> Self

Konstruiert einen Reader ueber den gegebenen Slice.

pub fn endianness(&self) -> Endianness

Aktuelle Endianness.

pub fn position(&self) -> usize

Aktuelle Position im Stream.

pub fn remaining(&self) -> usize

Verbleibende Bytes bis zum Ende.

pub fn align(&mut self, alignment: usize) -> Result<(), DecodeError>

Skipt Padding bis zur naechsten alignment-Boundary.

Errors

UnexpectedEof, wenn nicht genug Bytes fuer das Padding da sind.

pub fn read_bytes(&mut self, n: usize) -> Result<&'a [u8], DecodeError>

Liest exakt n Bytes als Slice (ohne Alignment).

Errors

UnexpectedEof.

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

Liest ein einzelnes Byte.

Errors

UnexpectedEof.

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

Aligned + liest u16.

Errors

UnexpectedEof.

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

Aligned + liest u32.

Errors

UnexpectedEof.

pub fn read_u64(&mut self) -> Result<u64, DecodeError>

Aligned + liest u64.

Errors

UnexpectedEof.

pub fn read_string(&mut self) -> Result<String, DecodeError>

Liest einen CDR-String (§9.3.2.7): 4-byte length (inkl. Null- Terminator) + UTF-8 Bytes + 1 Null-Byte. Gibt den String ohne Terminator zurueck.

Errors

UnexpectedEof bei zu kurzen Daten; InvalidData bei nicht-UTF-8 Bytes, fehlendem Null-Terminator oder length == 0.
