Enum PathComponent 

pub enum PathComponent {
    Key(BindingsName<'static>),
    Index(i64),
    KeyExpr(Box<ValueExpr>),
    IndexExpr(Box<ValueExpr>),
}

Represents a path component in a plan.

Variants

Key(BindingsName<'static>)

E.g. b in a.b

Index(i64)

E.g. 4 in a[4]

KeyExpr(Box<ValueExpr>)

IndexExpr(Box<ValueExpr>)

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 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.
