Variants

Array

Variable-length array type (Array(T)).

Assign

Assignment expression (used in Enum definitions).

Null

Null literal.

Nullable

Nullable wrapper type (Nullable(T)).

Number

Numeric literal (e.g. precision, scale, fixed string size).

String

String literal.

Terminal

Terminal (leaf) type with no parameters (e.g. Int32, UUID).

Tuple

Tuple type (Tuple(T1, T2, ...)).

Enum

LowCardinality

Dictionary-encoded type (LowCardinality(T)).

SimpleAggregateFunction

Simple aggregate function type.

Map

Key-value map type (Map(K, V)).

Trait Implementations

impl Clone for TypeMeta

fn clone(&self) -> TypeMeta

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TypeMeta

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

Formats the value using the given formatter.

impl PartialEq for TypeMeta

fn eq(&self, other: &TypeMeta) -> 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.
