Struct ThreadLocalEncoder 

pub struct ThreadLocalEncoder<'a> { /* private fields */ }

Available on crate feature dial9 only.

Scoped encoder for writing events into the thread-local trace buffer.

Provides access to string interning and event encoding. The borrow lifetime ensures that InternedString handles created via intern_string are used within the same batch — they become invalid after the buffer flushes.

You don’t construct this directly; it’s passed to Encodable::encode.

Implementations

impl ThreadLocalEncoder<'_>

pub fn intern_string(&mut self, s: &str) -> InternedString

Intern a string into the trace’s string pool, returning a compact handle.

If the string was already interned in this batch, returns the existing handle (no duplicate wire data). The returned InternedString is only valid for encoding within this same Encodable::encode call.

pub fn intern_stack_frames(&mut self, frames: &[u64]) -> InternedStackFrames

Intern a stack-frame vector into the trace’s stack pool, returning a compact handle.

If the stack was already interned in this batch, returns the existing handle (no duplicate wire data). The returned InternedStackFrames is only valid for encoding within this same Encodable::encode call.

pub fn encode(&mut self, event: &impl TraceEvent)

Encode a TraceEvent struct into the buffer.

Trait Implementations

impl Debug for ThreadLocalEncoder<'_>

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

Formats the value using the given formatter.
