Enum SemanticType

    ReplicaId,
    SchemaId,
    DatabaseId,
    RoleId,
    NetworkPolicyId,

    ByteCount,
    RecordCount,
    CreditRate,
    SqlDefinition,
    RedactedSqlDefinition,
}

Semantic type annotation for a column in a builtin catalog relation.

These are compile-time metadata used by the catalog ontology layer to describe the meaning of a column (e.g., that it contains a catalog item ID or a role ID). Possible values correspond to the entries in SEMANTIC_TYPE_DEFS in the mz-catalog crate.

Trait Implementations

impl Clone for SemanticType

fn clone(&self) -> SemanticType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SemanticType

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

Formats the value using the given formatter.

impl Display for SemanticType

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

Formats the value using the given formatter.

impl Hash for SemanticType

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 Ord for SemanticType

fn cmp(&self, other: &SemanticType) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for SemanticType

fn eq(&self, other: &SemanticType) -> 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 PartialOrd for SemanticType

fn partial_cmp(&self, other: &SemanticType) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for SemanticType

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for SemanticType

impl Eq for SemanticType

impl StructuralPartialEq for SemanticType
