Struct Schema 

pub struct Schema {
    pub version: String,
    pub attributes: IndexMap<AttributeId, AttributeSchema>,
    pub predicates: IndexMap<PredicateId, PredicateSignature>,
}

Fields

version: String

attributes: IndexMap<AttributeId, AttributeSchema>

predicates: IndexMap<PredicateId, PredicateSignature>

Implementations

impl Schema

pub fn new(version: impl Into<String>) -> Self

pub fn register_attribute( &mut self, attribute: AttributeSchema, ) -> Result<(), SchemaError>

pub fn register_predicate( &mut self, predicate: PredicateSignature, ) -> Result<(), SchemaError>

pub fn attribute(&self, id: &AttributeId) -> Option<&AttributeSchema>

pub fn predicate(&self, id: &PredicateId) -> Option<&PredicateSignature>

pub fn validate_predicate_arity( &self, id: &PredicateId, arity: usize, ) -> Result<(), SchemaError>

Trait Implementations

impl Clone for Schema

fn clone(&self) -> Schema

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Schema

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

Formats the value using the given formatter.

impl Default for Schema

fn default() -> Schema

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Schema

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Schema

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
