Struct ColumnDef 

pub struct ColumnDef {
    pub name: String,
    pub data_type: DataType,
    pub nullable: bool,
    pub default: Option<Expr>,
    pub primary_key: bool,
    pub unique: bool,
    pub autoincrement: bool,
}

A column definition for CREATE TABLE.

Fields

name: String

Column name.

data_type: DataType

Data type.

nullable: bool

Whether the column is nullable.

default: Option<Expr>

Default value expression.

primary_key: bool

Whether this is a primary key.

unique: bool

Whether this column is unique.

autoincrement: bool

Whether this column auto-increments.

Implementations

impl ColumnDef

pub fn new(name: impl Into<String>, data_type: DataType) -> Self

Creates a new column definition.

pub fn not_null(self) -> Self

Sets the column as NOT NULL.

pub fn primary_key(self) -> Self

Sets the column as PRIMARY KEY.

pub fn unique(self) -> Self

Sets the column as UNIQUE.

pub fn autoincrement(self) -> Self

Sets the column as AUTOINCREMENT.

pub fn default(self, expr: Expr) -> Self

Sets the default value.

Trait Implementations

impl Clone for ColumnDef

fn clone(&self) -> ColumnDef

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ColumnDef

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

Formats the value using the given formatter.

impl PartialEq for ColumnDef

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