Implementations

impl CatalogItemType

pub fn conflicts_with_type(&self) -> bool

Reports whether the given type of item conflicts with items of type CatalogItemType::Type.

In PostgreSQL, even though types live in a separate namespace from other schema objects, creating a table, view, or materialized view creates a type named after that relation. This prevents creating a type with the same name as a relational object, even though types and relational objects live in separate namespaces. (Indexes are even weirder; while they don’t get a type with the same name, they get an entry in pg_class that prevents record types of the same name as the index, but not other types of types, like enums.)

We don’t presently construct types that mirror relational objects, though we likely will need to in the future for full PostgreSQL compatibility (see #23789). For now, we use this method to prevent creating types and relational objects that have the same name, so that it is a backwards compatible change in the future to introduce a type named after each relational object in the system.

Trait Implementations

impl Clone for CatalogItemType

fn clone(&self) -> CatalogItemType

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CatalogItemType

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for CatalogItemType

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for CatalogItemType

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

Formats the value using the given formatter.

impl From<CatalogItemType> for ObjectType

fn from(value: CatalogItemType) -> Self

Converts to this type from the input type.

impl Hash for CatalogItemType

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 CatalogItemType

fn cmp(&self, other: &CatalogItemType) -> 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 + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq<CatalogItemType> for ObjectType

fn eq(&self, other: &CatalogItemType) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialEq<ObjectType> for CatalogItemType

Whether a SQL object type can be interpreted as matching the type of the given catalog item. For example, if v is a view, DROP SOURCE v should not work, since Source and View are non-matching types.

For now tables are treated as a special kind of source in Materialize, so just allow TABLE to refer to either.

fn eq(&self, other: &ObjectType) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialEq for CatalogItemType

fn eq(&self, other: &CatalogItemType) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for CatalogItemType

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

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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

impl Serialize for CatalogItemType

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
