This came up in omicron, where we wanted to add a probe for raw bytes. A workaround is to use integers; e.g.,
#[usdt::provider(provider = "blahblah")]
mod probes {
fn raw_bytes(
_data: u64, // TODO actually a `*const u8`, but that isn't currently allowed by usdt
_len: u64, // length of data
) {}
}which functions correctly from the dtrace side but is a little awkward on the Rust side.
