Struct DatabaseEvent 

pub struct DatabaseEvent<'db> { /* private fields */ }

Available on macOS only.

A single hardware performance counter event from the PMC database.

Each event describes one thing the CPU can count: retired instructions, cache misses, branch mispredictions, micro-ops, and so on. The name is the hardware-specific identifier (e.g. "INST_ALL"), while alias provides a human-readable label when one exists (e.g. "Instructions").

Implementations

impl<'db> DatabaseEvent<'db>

pub const fn name(&self) -> &'db str

Unique event name, e.g. "INST_ALL".

pub const fn description(&self) -> Option<&'db str>

Human-readable description, if available.

pub const fn errata(&self) -> Option<&'db str>

Errata notes, if any.

pub const fn alias(&self) -> Option<&'db str>

Human-readable alias, e.g. "Instructions", "Cycles".

pub const fn fallback(&self) -> Option<&'db str>

Fallback event name for fixed counters.

pub const fn is_fixed(&self) -> bool

Whether this event is bound to a fixed counter register.

The framework sets bit 0 of the event’s flags field during _event_init when the plist contains a "fixed_counter" key.
