[−][src]Module tracers_codegen::proc_macros
This module is where the implementation of the probe-related proc macros are. The actual
proc macro is in the tracers-macros
crate because proc macro crates can only export proc
macros and nothing else. That's an inconvenient restriction, especially since there's quite a
lot of overlap between the macro code and the build-time probe code generation logic. Hence,
this bifurcation.
Functions
init_provider_impl | |
probe_impl | Translates what looks to be an explicit call to the associated function corresponding to a probe on a provider trait, into something which at runtime will most efficiently attempt to access the global static instance of the probe and, if it's enabled, evaluate the args and fire the probe. |
report_error | Uses the |
tracer_impl | Actual implementation of the macro logic, factored out of the proc macro itself so that it's more testable |
