Struct Calls 

pub struct Calls(/* private fields */);

A trace sink that keeps the host calls a run made, in order.

What it is for is the deliverable that says every invocation and trace is linked to an application request identifier. Both reviews operations take that identifier as their first argument, so every HostCall event carries it, and Calls::for_request is the query that shows it.

Implementations

impl Calls

pub fn all(&self) -> Vec<RecordedCall>

Every call recorded, as module, op, and the first argument when it was a string.

pub fn for_request(&self, request: &str) -> Vec<String>

The operations recorded under request, in order.

Trait Implementations

impl Default for Calls

fn default() -> Calls

Returns the “default value” for a type.

impl TraceSink for Calls

fn record(&self, event: TraceEvent)

Records one event. Must not panic: a broken trace sink should degrade the trace, not the program being traced.

fn is_recording(&self) -> bool

Whether anything will read what is recorded.
