Struct Relation 

pub struct Relation {
    pub name: String,
    pub description: Option<String>,
    pub from: String,
    pub to: String,
    pub unique: bool,
    pub fields: Vec<Field>,
}

A graph edge definition (relation) — a typed, directed connection between two Records.

Maps to a SurrealDB DEFINE TABLE ... TYPE RELATION IN <from> OUT <to> statement. A relation may carry its own Fields (a “property edge”).

Fields

name: String

Relation name (e.g. "derivedFrom").

description: Option<String>

Optional documentation string (description="...").

from: String

The record name at the in end of the edge.

to: String

The record name at the out end of the edge.

unique: bool

Whether each (from, to) pair must be unique.

fields: Vec<Field>

Edge-property fields in source order.

Trait Implementations

impl Clone for Relation

fn clone(&self) -> Relation

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Relation

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

Formats the value using the given formatter.

impl PartialEq for Relation

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