Struct Relation 

pub struct Relation {
    pub kind: RelationKind,
    pub target: RelationTarget,
    pub transitive: bool,
    pub max_depth: Option<u32>,
    pub scope: TraversalScope,
    pub as: Option<String>,
}

Single relation condition

Fields

kind: RelationKind

Relation type

target: RelationTarget

Target query (simplified for now - will be expanded)

transitive: bool

Include transitive relations

max_depth: Option<u32>

Maximum traversal depth for transitive queries (None = unlimited)

scope: TraversalScope

Traversal scope for transitive queries

as: Option<String>

Bind result to variable

Implementations

impl Relation

pub fn new(kind: RelationKind, target: RelationTarget) -> Self

Create a new relation

pub fn transitive(self) -> Self

Set transitive mode

pub fn with_max_depth(self, depth: u32) -> Self

Set max depth

pub fn with_scope(self, scope: TraversalScope) -> Self

Set scope

pub fn bind(self, var: impl Into<String>) -> Self

Bind to variable

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<'de> Deserialize<'de> for Relation

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl JsonSchema for Relation

fn schema_name() -> Cow<'static, str>

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn inline_schema() -> bool

Whether JSON Schemas generated for this type should be included directly in parent schemas, rather than being re-used where possible using the $ref keyword.

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.

impl Serialize for Relation

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
