pub const KTSTR_JEMALLOC_PROBE_BINARY_ENV: &str = "KTSTR_JEMALLOC_PROBE_BINARY";Expand description
Name of the environment variable that points at a probe binary
for jemalloc-feature detection. Empty / unset leaves the probe
binary unwired (the crate::test_support::runtime
builder-wiring site calls .jemalloc_probe_binary() only on
set+non-empty — there is no which-based fallback). Tests
that need the probe set this var via #[ctor] before the
harness runs (see tests/jemalloc_probe_tests.rs).
