pub struct Relation {
    pub name: SqlIdentifier,
    pub fields: Vec<Field>,
    pub materialized: bool,
    pub properties: BTreeMap<String, PropertyValue>,
}

A SQL table or view. It has a name and a list of fields.

Matches the Calcite JSON format.

Fields

name: SqlIdentifier

fields: Vec<Field>

materialized: bool

properties: BTreeMap<String, PropertyValue>

Implementations

impl Relation

pub fn empty() -> Self

pub fn new( name: SqlIdentifier, fields: Vec<Field>, materialized: bool, properties: BTreeMap<String, PropertyValue>, ) -> Self

pub fn field(&self, name: &str) -> Option<&Field>

Lookup field by name.

pub fn has_lateness(&self) -> bool

pub fn get_property(&self, name: &str) -> Option<&str>

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 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.

impl<'__s> ToSchema<'__s> for Relation

fn schema() -> (&'__s str, RefOr<Schema>)

Return a tuple of name and schema or reference to a schema that can be referenced by the name or inlined directly to responses, request bodies or parameters.

fn aliases() -> Vec<(&'__s str, Schema)>

Optional set of alias schemas for the ToSchema::schema.

impl Eq for Relation
