Implementations

impl<C> ResourceCommand<C>

pub fn key(&self) -> &ResourceKey

Returns the resource key for this command.

pub fn scope(&self) -> ScopeId

Returns the scope associated with this command.

Trait Implementations

impl<C: Clone> Clone for ResourceCommand<C>

fn clone(&self) -> ResourceCommand<C>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<C: Debug> Debug for ResourceCommand<C>

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

Formats the value using the given formatter.

impl<C: Eq> Eq for ResourceCommand<C>

impl<C: PartialEq> PartialEq for ResourceCommand<C>

fn eq(&self, other: &ResourceCommand<C>) -> 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.
