Struct mz_catalog::durable::objects::SystemObjectMapping

pub struct SystemObjectMapping {
    pub description: SystemObjectDescription,
    pub unique_identifier: SystemObjectUniqueIdentifier,
}

Functions can share the same name as any other catalog item type within a given schema. For example, a function can have the same name as a type, e.g. ‘date’. As such, system objects are keyed in the catalog storage by the tuple (schema_name, object_type, object_name), which is guaranteed to be unique.

Trait Implementations

impl Clone for SystemObjectMapping

fn clone(&self) -> SystemObjectMapping

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SystemObjectMapping

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

Formats the value using the given formatter.

impl DurableType for SystemObjectMapping

type Key = GidMappingKey

type Value = GidMappingValue

fn into_key_value(self) -> (Self::Key, Self::Value)

Consume and convert Self into a (Key, Value) key-value pair.

fn from_key_value(key: Self::Key, value: Self::Value) -> Self

Consume and convert a (Key, Value) key-value pair back into a Self value.

fn key(&self) -> Self::Key

Produce a Key from self. This may involve cloning/copying required fields.

impl Ord for SystemObjectMapping

fn cmp(&self, other: &SystemObjectMapping) -> 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 for SystemObjectMapping

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

fn partial_cmp(&self, other: &SystemObjectMapping) -> 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.
