Implementations

impl FieldRef

pub fn column(table: &str, column: &str) -> Self

Create a table column reference

pub fn node_prop(alias: &str, property: &str) -> Self

Create a node property reference

pub fn node_id(alias: &str) -> Self

Create a node ID reference

pub fn edge_prop(alias: &str, property: &str) -> Self

Create an edge property reference

Trait Implementations

impl Clone for FieldRef

fn clone(&self) -> FieldRef

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FieldRef

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

Formats the value using the given formatter.

impl Hash for FieldRef

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 FieldRef

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