Crate hitrace_sys 

Raw bindings for the HiTrace tracing system on OpenHarmony

The official Hitrace NDK guidelines describe the available API. Rust users should likely not use this crate directly, but instead use an abstraction on top of this crate.

Feature flags

OpenHarmony API level

This crate by default exposes bindings for API-level 10. Optionally enable one of the api-* features to get access to bindings for newer OpenHarmony versions.

• api-10 (enabled by default) — No effect. API-10 bindings can’t be deselected. The feature exists for internal purposes.
• api-11 — Enables bindings for OpenHarmony API-level 11 (No additions)
• api-12 — Enables bindings for OpenHarmony API-level 12
• api-13 — Enables bindings for OpenHarmony API-level 13 (No changes)
• api-14 — Enables bindings for OpenHarmony API-level 14 (No changes)
• api-15 — Enables bindings for OpenHarmony API-level 15 (No changes)
• api-16 — Enables bindings for OpenHarmony API-level 16 (No changes).
• api-17 — Enables bindings for OpenHarmony API-level 17 (No changes).
• api-18 — Enables bindings for OpenHarmony API-level 18 (No changes).
• api-19 — Enables bindings for OpenHarmony API-level 19. (No changes)
• api-20 — Enables bindings for OpenHarmony API-level 20. (No changes)
• api-21 — Enables bindings for OpenHarmony API-level 21.
