perf-event-open-sysBased on Linux kernel headers packaged by Fedora as kernel-headers-5.18.4-200.fc36.
Fix build for Android, x86_64-unknown-linux-musl.
Remove redundant prefixes from bindings constants derived from enums in the Linux kernel headers.
For example, the kernel headers have the definition:
/*
* attr.type
*/
enum perf_type_id {
PERF_TYPE_HARDWARE = 0,
PERF_TYPE_SOFTWARE = 1,
PERF_TYPE_TRACEPOINT = 2,
...
};
This crate used to render the above as constants like this:
pub const perf_type_id_PERF_TYPE_HARDWARE: perf_type_id = 0; pub const perf_type_id_PERF_TYPE_SOFTWARE: perf_type_id = 1; pub const perf_type_id_PERF_TYPE_TRACEPOINT: perf_type_id = 2; ...
The names incorporate the names of both the C enum and its constants. But since the constants' names are already prefixed (necessary because C places enumeration constants in the ‘ordinary identifier’ namespace), this is redundant.
In v3.0.0, these constants are rendered in Rust like this:
pub const PERF_TYPE_HARDWARE: perf_type_id = 0; pub const PERF_TYPE_SOFTWARE: perf_type_id = 1; pub const PERF_TYPE_TRACEPOINT: perf_type_id = 2;
