Enum CallstackField 

pub enum CallstackField {
    Callstack(Callstack),
    CallstackIid(u64),
}

Callstack associated with this event. This captures the program stack at the time the event occurred, useful for understanding what code path led to the event.

Two variants are supported:

• callstack: Inline callstack data (simpler when trace size is not a concern or callstacks are unique)
• callstack_iid: Reference to an interned Callstack in InternedData (efficient for repeated callstacks)

Only one of these fields should be set.

Variants

Callstack(Callstack)

Inline callstack data. Use this for simplicity when interning is not needed (e.g., for unique callstacks or when trace size is not critical).

CallstackIid(u64)

Reference to interned Callstack (see InternedData.callstacks). This is the efficient option when callstacks are repeated.

Note: iids always start from 1. A value of 0 is considered “not set”.

Implementations

impl CallstackField

pub fn encode<B>(&self, buf: &mut B)

where B: BufMut,

Encodes the message to a buffer.

pub fn merge<B>( field: &mut Option<CallstackField>, tag: u32, wire_type: WireType, buf: &mut B, ctx: DecodeContext, ) -> Result<(), DecodeError>

where B: Buf,

Decodes an instance of the message from a buffer, and merges it into self.

pub fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

Trait Implementations

impl Clone for CallstackField

fn clone(&self) -> CallstackField

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for CallstackField

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

Formats the value using the given formatter.

impl PartialEq for CallstackField

fn eq(&self, other: &CallstackField) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
