Enum AttributeAccess

pub enum AttributeAccess {
    EntityLUB(EntityLUB, Vec<SmolStr>),
    Context(EntityUID, Vec<SmolStr>),
    Other(Vec<SmolStr>),
}

Contains more detailed information about an attribute access when it occurs on an entity type expression or on the context variable. Track a Vec of attributes rather than a single attribute so that on principal.foo.bar can report that the record attribute foo of an entity type (e.g., User) needs attributes bar instead of giving up when the immediate target of the attribute access is not a entity.

Variants

EntityLUB(EntityLUB, Vec<SmolStr>)

The attribute access is some sequence of attributes accesses eventually targeting an EntityLUB.

Context(EntityUID, Vec<SmolStr>)

The attribute access is some sequence of attributes accesses eventually targeting the context variable. The context being accessed is identified by the EntityUID for the associated action.

Other(Vec<SmolStr>)

Other cases where we do not attempt to give more information about the access. This includes any access on the AnyEntity type and on record types other than the context variable.

Trait Implementations

impl Clone for AttributeAccess

fn clone(&self) -> AttributeAccess

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for AttributeAccess

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

Formats the value using the given formatter.

impl Display for AttributeAccess

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

Formats the value using the given formatter.

impl Hash for AttributeAccess

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for AttributeAccess

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