Struct OutputStream 

pub struct OutputStream { /* private fields */ }

A growable byte buffer for writing FIT binary.

Implementations

impl OutputStream

pub fn new() -> Self

pub fn with_capacity(cap: usize) -> Self

pub fn position(&self) -> usize

Current write position (length of the buffer).

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

Borrow the written bytes.

pub fn into_bytes(self) -> Vec<u8>

Consume the stream and return the buffer.

pub fn write_u8(&mut self, v: u8)

Write a single byte.

pub fn write_u16(&mut self, v: u16)

Write a u16 in little-endian byte order.

pub fn write_u32(&mut self, v: u32)

Write a u32 in little-endian byte order.

pub fn write_i16(&mut self, v: i16)

Write a i16 in little-endian byte order.

pub fn write_i32(&mut self, v: i32)

Write a i32 in little-endian byte order.

pub fn write_u64(&mut self, v: u64)

Write a u64 in little-endian byte order.

pub fn write_i64(&mut self, v: i64)

Write a i64 in little-endian byte order.

pub fn write_bytes(&mut self, bytes: &[u8])

Write raw bytes.

pub fn patch(&mut self, offset: usize, bytes: &[u8])

Patch bytes at a specific offset (for backpatching header fields).

Trait Implementations

impl Debug for OutputStream

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

impl Default for OutputStream

fn default() -> OutputStream

Returns the “default value” for a type.
