Struct CustomTypeMeta 

pub struct CustomTypeMeta {
    pub name: String,
    pub base_type_sql: String,
    pub created_at_micros: u64,
}

Metadata about a custom type (CREATE TYPE/DOMAIN).

Stored in the system catalog (table 0) and serialized using bitcode. Represents type aliases like CREATE TYPE custom_type AS integer.

Fields

name: String

Human-readable type name (case-preserved, stored lowercase in catalog).

base_type_sql: String

SQL representation of the base data type (e.g., “INTEGER”, “VARCHAR(100)”). Stored as string to avoid Arrow DataType serialization complexity.

created_at_micros: u64

When the type was created (microseconds since epoch).

Trait Implementations

impl Clone for CustomTypeMeta

fn clone(&self) -> CustomTypeMeta

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CustomTypeMeta

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

Formats the value using the given formatter.

impl PartialEq for CustomTypeMeta

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