Struct OleanWriter 

pub struct OleanWriter { /* private fields */ }

Streaming binary writer for the OleanC format.

Implementations

impl OleanWriter

pub fn new() -> Self

Create a new, empty writer.

pub fn write_header(&mut self, decl_count: u32) -> &mut Self

Write the OleanC file header.

The metadata section offset is set to HEADER_SIZE (immediately after the header) when no additional body is present; callers may update it afterwards.

pub fn write_string(&mut self, s: &str) -> &mut Self

Write a length-prefixed UTF-8 string (u32 length + bytes).

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

Write a single byte.

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

Write a u32 in little-endian order.

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

Write a u64 in little-endian order.

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

Write an i64 in little-endian order.

pub fn write_bool(&mut self, v: bool) -> &mut Self

Write a bool as a single byte (0 or 1).

pub fn len(&self) -> usize

Return the current number of bytes written.

pub fn is_empty(&self) -> bool

Return true if no bytes have been written yet.

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

Consume the writer and return the accumulated bytes.

impl Default for OleanWriter

fn default() -> Self

Returns the “default value” for a type.
