Enum EdgeRelation 

pub enum EdgeRelation {

}

Closed set of 13 canonical edge relations (ADR-002, ADR-021).

No Default — every edge requires an explicit relation. Wire format: snake_case strings (e.g. "part_of", "introduced_by").

Implementations

impl EdgeRelation

pub const ALL: [Self; 13]

All 13 canonical relations in ADR-002 table order.

pub const fn category(&self) -> EdgeCategory

The category this relation belongs to.

pub const fn as_str(&self) -> &'static str

Canonical snake_case name as stored in the database.

Trait Implementations

impl Clone for EdgeRelation

fn clone(&self) -> EdgeRelation

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EdgeRelation

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for EdgeRelation

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for EdgeRelation

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

Formats the value using the given formatter.

impl FromStr for EdgeRelation

type Err = UnknownVariant

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Hash for EdgeRelation

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 EdgeRelation

fn eq(&self, other: &EdgeRelation) -> 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 EdgeRelation

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
