Struct TraceMeta
#[non_exhaustive]pub struct TraceMeta {
pub root_addr: Option<*const c_void>,
pub trace_leaf_addr: *const c_void,
}Available on
tokio_unstable and Linux and crate feature rt and crate feature taskdump and (AArch64 or s390x or x86 or x86-64) only.Metadata passed into the trace_leaf callback for trace_with
Fields (Non-exhaustive)
Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional
Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.root_addr: Option<*const c_void>The root boundary address set by Root::poll if any.
When using unwinding the stack, this is the address at which stack walking should stop. It corresponds to the Root::poll function pointer.
trace_leaf_addr: *const c_voidThe address of the internal trace_leaf function that triggered this callback.
When capturing a backtrace, use this as the lower bound — frames at or below this address are internal implementation details and should be excluded.
