tracers-libstapsdt-sys has no features set by default.
by default, building libstapsdt is disabled. It must be explicitly enabled
- enabled =
if this feature is enabled, then the build.rs will try to build the libstapsdt binaries.
if the build fails, this crate's build will still succeed
The success or failure of the build will be communicated via a variable in cargo,
which dependent crates can resolve with DEP_LIBELF_SYS_SUCCEEDED
- required =
If this feature is enabled, it implies
enabled, and also will cause the build to fail if libstapsdt cannot be built
Features from optional dependencies
In crates that don't use the
dep: syntax, optional dependencies automatically become Cargo features.
