Struct PrintfBuffer 

pub struct PrintfBuffer { /* private fields */ }

GPU-side printf emulation buffer.

The buffer layout is a simple framed protocol:

[entry_count: u32_le]
repeated entry_count times:
  [thread_x: u32_le] [thread_y: u32_le] [thread_z: u32_le]
  [block_x:  u32_le] [block_y:  u32_le] [block_z:  u32_le]
  [fmt_len:  u32_le] [fmt_bytes: u8 * fmt_len]
  [arg_count: u32_le]
  repeated arg_count times:
    [tag: u8]  0=Int(i64_le), 1=Float(f64_le), 2=String(u32_le len + bytes)

Implementations

impl PrintfBuffer

pub fn new(buffer_size: usize) -> Self

Create a printf buffer descriptor with the given maximum size.

pub fn buffer_size(&self) -> usize

Returns the configured buffer size.

pub fn parse_entries(&self, raw: &[u8]) -> Vec<PrintfEntry>

Parse a raw byte buffer into structured printf entries.

Returns an empty vec if the buffer is too small or malformed.

Trait Implementations

impl Debug for PrintfBuffer

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

Formats the value using the given formatter.
