Trait Implementations

impl Clone for AplElementType

fn clone(&self) -> AplElementType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AplElementType

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for AplElementType

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl ElementType for AplElementType

type Role = UniversalElementRole

The associated role type for this element kind.

fn is_root(&self) -> bool

Returns true if this element represents the root of the parsed tree.

fn is_error(&self) -> bool

Returns true if this element represents an error condition.

fn role(&self) -> Self::Role

Returns the general syntactic role of this element.

fn is_role(&self, role: Self::Role) -> bool

Returns true if this element matches the specified language-specific role.

fn is_universal(&self, role: UniversalElementRole) -> bool

Returns true if this element matches the specified universal role.

impl From<AplTokenType> for AplElementType

fn from(token_type: AplTokenType) -> Self

Converts to this type from the input type.

impl Hash for AplElementType

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 AplElementType

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

impl Serialize for AplElementType

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for AplElementType

impl Eq for AplElementType
