Trait Implementations

impl AsRef<str> for NodeType

fn as_ref(&self) -> &str

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for NodeType

fn clone(&self) -> NodeType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NodeType

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

Formats the value using the given formatter.

impl Display for NodeType

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

Formats the value using the given formatter.

impl<'_enum> From<&'_enum AnyParseNode> for NodeType

fn from(val: &'_enum AnyParseNode) -> NodeType

Converts to this type from the input type.

impl From<AnyParseNode> for NodeType

fn from(val: AnyParseNode) -> NodeType

Converts to this type from the input type.

impl Hash for NodeType

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 NodeType

fn eq(&self, other: &NodeType) -> 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 Copy for NodeType

impl Eq for NodeType

impl StructuralPartialEq for NodeType
