span-methods: Span Object Methods

In ot: 'Open Tracing'

Description

These define the core methods required by the specification for using spans.

Usage

setTags(span, ...)

baggage(span, ...)

baggage(span, ...) <- value

getContext(span, ...)

otlog(span, ..., timestamp = Sys.time())

log(span, ..., timestamp = Sys.time())

finish(span, finishTime = Sys.time())

Arguments

span	a span object
...	defined by implementation
value	the baggage data
timestamp	a POSIXct timestamp for the beginning of a span
finishTime	a POSIXct timestamp for the end of a span

Value

the span, except for getContext which returns the span's parent context and baggage, which returns any baggage objects.

Note

Developers should implement the otlog method only for their spans - log is a generic method used by R for logarithms. ot::log is an alias for convenience only.

Examples

s <- ot::startSpan(ot::getNoOpTracer())
ot::setTags(s, foo=1)
ot::baggage(s) <- list(ctx=1)
ot::getContext(s)
ot::otlog(s, foo=1)
ot::log(s, bar=2)
ot::finish(s)
ot::baggage(s)
