Enum PathComponent 

pub enum PathComponent {
    Field(AstField),
    Index(usize),
}

Represents a path component in an AST navigation path. Components that make up a path through the AST. Enables precise navigation to any AST node.

Variants

Field(AstField)

Field access by AST field enum (type-safe)

Index(usize)

Array/Vec index access

Trait Implementations

impl Clone for PathComponent

fn clone(&self) -> PathComponent

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PathComponent

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

Formats the value using the given formatter.

impl Display for PathComponent

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

Formats the value using the given formatter.

impl PartialEq for PathComponent

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