Enum TemplateResourceConstraint 

pub enum TemplateResourceConstraint {
    Any,
    In(Option<EntityUid>),
    Eq(Option<EntityUid>),
}

Head constraint on policy resources for templates.

Variants

Any

Un-constrained

In(Option<EntityUid>)

Must be In the given EntityUid. If None, then it is a template slot.

Eq(Option<EntityUid>)

Must be equal to the given EntityUid If None, then it is a template slot.

Implementations

impl TemplateResourceConstraint

pub fn has_slot(&self) -> bool

Does this constraint contain a slot?

Trait Implementations

impl Clone for TemplateResourceConstraint

fn clone(&self) -> TemplateResourceConstraint

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TemplateResourceConstraint

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

Formats the value using the given formatter.

impl PartialEq for TemplateResourceConstraint

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