Enum MapProjectionItemKind 

pub enum MapProjectionItemKind {
    PropertySelector,
    Literal,
    AllPropertiesSpread,
    AllBoundVarsSpread,
}

The four shapes a map-projection item can take.

Variants

PropertySelector

.NAME — property selector. Pulls subject.NAME into the projection under key NAME.

Literal

key: Expr — literal item. Inserts Expr under key key.

AllPropertiesSpread

.* — all-properties spread of the subject.

AllBoundVarsSpread

* — all-bound-vars spread (rare openCypher form).

Trait Implementations

impl Clone for MapProjectionItemKind

fn clone(&self) -> MapProjectionItemKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MapProjectionItemKind

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

Formats the value using the given formatter.

impl Hash for MapProjectionItemKind

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 MapProjectionItemKind

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