Struct CdrWriter 

pub struct CdrWriter { /* private fields */ }

Writes primitives as little-endian CDR, handling alignment padding.

The writer starts with the little-endian encapsulation header; each write aligns the cursor to the value’s size (measured from the start of the body) before appending the bytes.

Examples

use pamoja_ros2::msg::CdrWriter;

let mut w = CdrWriter::new();
w.write_f64(1.0);
// Four-byte header plus eight bytes for the double.
assert_eq!(w.into_bytes().len(), 12);

Implementations

impl CdrWriter

pub fn new() -> Self

Creates a writer primed with the little-endian CDR encapsulation header.

Returns

The writer.

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

Writes a 32-bit signed integer.

Arguments

• value - the integer to write.

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

Writes a 32-bit unsigned integer.

Arguments

• value - the integer to write.

pub fn write_f32(&mut self, value: f32)

Writes a 32-bit float.

Arguments

• value - the float to write.

pub fn write_f64(&mut self, value: f64)

Writes a 64-bit float.

Arguments

• value - the float to write.

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

Consumes the writer and returns the encoded bytes, header included.

Returns

The CDR-encoded buffer.
