Struct CounterMask

#[repr(C)]
pub struct CounterMask { /* private fields */ }

Counter index mask structure in SBI function calls for the PMU extension §11.

Implementations

impl CounterMask

pub const IGNORE_MASK: usize = 18_446_744_073_709_551_615usize

Special value to ignore the mask, and consider all bits as set.

pub const fn from_mask_base( counter_idx_mask: usize, counter_idx_base: usize, ) -> Self

Construct a CounterMask from mask value and base counter index.

pub const fn ignore_mask(&self) -> usize

Gets the special value for ignoring the mask parameter.

pub const fn into_inner(self) -> (usize, usize)

Returns mask and base parameters from the CounterMask.

pub const fn has_bit(self, counter: usize) -> bool

Returns whether the CounterMask contains the provided counter.

Trait Implementations

impl Clone for CounterMask

fn clone(&self) -> CounterMask

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for CounterMask

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for CounterMask

fn eq(&self, other: &CounterMask) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
