tracing-core 0.1.27

This release of tracing-core introduces a new DefaultCallsite type, which
can be used by instrumentation crates rather than implementing their own
callsite types. Using DefaultCallsite may offer reduced overhead from callsite
registration.

Added

  • DefaultCallsite, a pre-written Callsite implementation for use in
    instrumentation crates (#2083)
  • ValueSet::len and Record::len methods returning the number of fields in a
    ValueSet or Record (#2152)

Changed

  • Replaced lazy_static dependency with once_cell (#2147)

Documented

  • Added documentation to the callsite module (#2088, #2149)

Thanks to new contributors @jamesmunns and @james7132 for contributing to this
release!
