Struct NoMatcher

Source 
pub struct NoMatcher { /* private fields */ }
Expand description

An AssertionBuilder which does not yet have a span matcher.

A matcher consists of either a span name, or the target of a span itself, or potentially both. A span target refers to the tracing parlance, where “target” refers to the module path that a span is defined in.

Additionally, a span matcher can include specific fields that must be present on a span in order to match.
