Enum Priority

#[repr(u8)]
pub enum Priority {
    P1 = 1,
    P2 = 2,
    P3 = 3,
    P4 = 4,
}

Logical interrupt priority level.

P4 is the most urgent, and P1 is the least urgent priority.

Variants

P1 = 1

P2 = 2

P3 = 3

P4 = 4

Implementations

impl Priority

pub const fn from_numeric(prio: u8) -> Option<Self>

Creates the Priority from a numeric priority if possible.

pub const fn logical2hw(self) -> u8

Convert a logical priority (where higher priority number = higher priority level) to a hardware priority level (where lower priority number = higher priority level).

Taken from cortex-m-interrupt

See LICENSE-MIT for the license.

pub const fn hw2logical(prio: u8) -> Self

Convert a hardware priority level (where lower priority number = higher priority level) to a logical priority (where a higher priority number = higher priority level).

Panics

This method may only be used with allowed hardware priority levels. Ie,

• 0x00,
• 0x20,
• 0x40,
• and so on.

Any other value will cause a panic. To save yourself some trouble, use this method only with hardware priority values gotten directly from the NVIC.

Trait Implementations

impl Clone for Priority

fn clone(&self) -> Priority

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Priority

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

Formats the value using the given formatter.

impl Format for Priority

fn format(&self, f: Formatter<'_>)

Writes the defmt representation of self to fmt.

impl Ord for Priority

fn cmp(&self, other: &Priority) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Priority

fn eq(&self, other: &Priority) -> 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.

impl PartialOrd for Priority

fn partial_cmp(&self, other: &Priority) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
