Enum TraceRequest 

pub enum TraceRequest {
    StartFfi(StartFfiInfo),
    OverrideRetcode(i32),
}

An IPC request sent by the child process to the parent.

The sender for this channel should live on the child process.

Variants

StartFfi(StartFfiInfo)

Requests that tracing begins. Following this being sent, the child must wait to receive a Confirmation on the respective channel and then raise(SIGSTOP).

To avoid possible issues while allocating memory for IPC channels, ending the tracing is instead done via raise(SIGUSR1).

OverrideRetcode(i32)

Manually overrides the code that the supervisor will return upon exiting. Once set, it is permanent. This can be called again to change the value.

After sending this, the child must wait to receive a Confirmation.
