Struct FatalSerializer 

pub struct FatalSerializer { /* private fields */ }

The streaming fatal-envelope serializer and its fixed scratch space. A binary reserves one before evaluator allocation accounting begins, so a fatal projection is always emittable: emission streams JCS(envelope) and the trailing newline through the reserved staging buffer without materializing the wire.

Implementations

impl FatalSerializer

pub fn new() -> Self

Reserves the staging buffer and serializer scratch.

pub fn emit(&mut self, envelope: &Value, out: &mut dyn Write) -> Result<u64>

Streams the envelope’s wire (JCS(envelope) || LF) into the writer through the reserved scratch and returns the byte count.

Errors

The first writer error; the wire is incomplete in that case and the caller treats the emission as failed.

pub fn wire_bytes(&mut self, envelope: &Value) -> Vec<u8>

The materialized wire for a caller that must inspect the bytes (the wrapper’s acceptance): one counting pass sizes the allocation exactly, then one streaming pass fills it.

Trait Implementations

impl Default for FatalSerializer

fn default() -> Self

Returns the “default value” for a type.
