Enum BarewordRole 

#[non_exhaustive]
pub enum BarewordRole {
    Expression,
    QualifiedName,
    ModuleRequest,
    MethodReceiver,
    IndirectObject,
    HashKey,
}

Syntactic roles for parsed barewords.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Expression

Plain expression-position bareword with unresolved meaning.

QualifiedName

Qualified name such as Foo::Bar outside a more specific context.

ModuleRequest

Bareword used as a static require module target.

MethodReceiver

Bareword used as a class/object receiver for ->.

IndirectObject

Bareword used as the object in an indirect-object call.

HashKey

Bareword used as an autoquoted hash key.

Trait Implementations

impl Clone for BarewordRole

fn clone(&self) -> BarewordRole

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for BarewordRole

impl Debug for BarewordRole

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

Formats the value using the given formatter.

impl Eq for BarewordRole

impl Hash for BarewordRole

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 BarewordRole

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