Struct ByteStream 

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

A read cursor over a borrowed byte slice.

Implementations

impl<'a> ByteStream<'a>

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

Wrap a byte slice. Cursor starts at offset 0.

pub fn as_slice(&self) -> &'a [u8]

Underlying slice (full length, ignoring cursor).

pub fn position(&self) -> usize

Current cursor offset.

pub fn seek(&mut self, offset: usize) -> Result<(), FitError>

Move the cursor to an absolute offset. Returns an error if past end.

pub fn remaining(&self) -> usize

Number of bytes remaining after the cursor.

pub fn is_empty(&self) -> bool

True if cursor is at or past end of slice.

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

Read the next byte without advancing.

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

Read and consume the next byte.

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

Read and consume the next n bytes as a borrowed sub-slice.

pub fn read_array<const N: usize>(&mut self) -> Result<[u8; N], FitError>

Read and consume an exact N-byte array.

pub fn read_u16(&mut self, endian: Endian) -> Result<u16, FitError>

Read u16 in the requested endianness.

pub fn read_u32(&mut self, endian: Endian) -> Result<u32, FitError>

Read u32 in the requested endianness.

pub fn read_u16_le(&mut self) -> Result<u16, FitError>

Convenience: read u16 little-endian.

pub fn read_u32_le(&mut self) -> Result<u32, FitError>

Convenience: read u32 little-endian.

Trait Implementations

impl<'a> Clone for ByteStream<'a>

fn clone(&self) -> ByteStream<'a>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'a> Debug for ByteStream<'a>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
