Enum ColumnType 

pub enum ColumnType {
    Uuid,
    Varchar,
    VarcharN(u32),
    Boolean,
    DateTime,
    Json,
    Int,
    SmallInt,
    Text,
}

Abstract column type – each dialect maps this to a concrete SQL type.

Variants

Uuid

UUID type. Postgres: UUID.

Varchar

Variable-length string. Postgres: VARCHAR.

VarcharN(u32)

Variable-length string with max length. Postgres: VARCHAR(n).

Boolean

Boolean. Postgres: BOOLEAN.

DateTime

Timestamp with timezone. Postgres: TIMESTAMPTZ.

Json

JSON binary. Postgres: JSONB.

Int

32-bit integer. Postgres: INT.

SmallInt

16-bit integer. Postgres: SMALLINT.

Text

Text (unbounded). Postgres: TEXT.

Trait Implementations

impl Clone for ColumnType

fn clone(&self) -> ColumnType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ColumnType

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

Formats the value using the given formatter.

impl Hash for ColumnType

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 PartialEq for ColumnType

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