Enum SqlTy 

pub enum SqlTy {
    Boolean,
    Bigint,
    Double,
    Text,
}

The four SQL types a Beck scalar maps onto.

Deliberately four. Every one of them is a type OID a Postgres client already knows, so a driver never has to ask the catalogue what it just received — which matters more than breadth here, because there is no catalogue to ask (Schema::CATALOGUE is what stands in for one).

Variants

Boolean

Bigint

Double

Text

Implementations

impl SqlTy

pub fn oid(self) -> u32

The Postgres type OID, as it goes on the wire in a RowDescription.

pub fn width(self) -> i16

The width a fixed-size type has, or -1 for a variable one.

pub fn name(self) -> &'static str

Trait Implementations

impl Clone for SqlTy

fn clone(&self) -> SqlTy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SqlTy

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

Formats the value using the given formatter.

impl PartialEq for SqlTy

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