Enum FunctionTrace

}

A representation of the various trace messages a client thread can send us during normal tracing operation.

We use Cow instead of String because most strings should be zero-copy deserializable.

Variants

RegisterThread(ThreadRegistration)

A request to register this as a new thread.

NOTE: This must be sent as the first message from a new thread, and may not be sent twice by any thread.

Call

Fields

time: Duration

func_name: Cow<'event, str>

filename: Cow<'event, str>

linenumber: u32

This should be a NonZeroU32, but sometimes Python passes us things that seem like they should be NativeCalls instead. It’s easier to be liberal here and to handle this later.

Return

Fields

time: Duration

func_name: Cow<'event, str>

NativeCall

Fields

time: Duration

func_name: Cow<'event, str>

module_name: Cow<'event, str>

NativeReturn

Fields

time: Duration

func_name: Cow<'event, str>

Exception

Fields

time: Duration

exception_type: Cow<'event, str>

exception_value: Cow<'event, str>

filename: String

linenumber: NonZeroU32

Log

Fields

time: Duration

log_type: Cow<'event, str>

log_value: Cow<'event, str>

Import

Fields

time: Duration

module_name: Cow<'event, str>

Allocation

Fields

time: Duration

details: AllocationDetails
