Implementations

impl IntentLock

pub fn is_compatible(&self, other: &IntentLock) -> bool

Check if this lock is compatible with another lock

Trait Implementations

impl Clone for IntentLock

fn clone(&self) -> IntentLock

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for IntentLock

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

Formats the value using the given formatter.

impl PartialEq for IntentLock

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