Enum Ownership

pub enum Ownership {
    Owned {
        priority: u8,
    },
    CoOwned {
        priority: u8,
    },
    Contended {
        ceiling: u8,
    },
}

Resource ownership

Variants

Owned

Owned by a single task

Fields

priority: u8

CoOwned

“Co-owned” by more than one task; all of them have the same priority

Fields

priority: u8

Priority of the tasks that co-own this resource

Contended

Contended by more than one task; the tasks have different priorities

Fields

ceiling: u8

Priority ceiling

Implementations

impl Ownership

pub fn needs_lock(&self, priority: u8) -> bool

Whether this resource needs to a lock at this priority level

pub fn is_owned(&self) -> bool

Whether this resource is exclusively owned

Trait Implementations

impl Clone for Ownership

fn clone(&self) -> Ownership

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Ownership

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

Formats the value using the given formatter.

impl PartialEq for Ownership

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