Struct ColumnDef 

pub struct ColumnDef {
    pub name: String,
    pub col_type: ColumnType,
    pub nullable: bool,
    pub default: Option<Value>,
    pub primary_key: bool,
    pub auto_increment: bool,
    pub unique: bool,
    pub index: bool,
}

A column definition in the lightweight schema DSL.

Fields

name: String

The column name.

col_type: ColumnType

The logical column type.

nullable: bool

Whether the column accepts NULL values.

default: Option<Value>

The default value when one is configured.

primary_key: bool

Whether this column is the primary key.

auto_increment: bool

Whether the column auto-increments.

unique: bool

Whether the column is unique.

index: bool

Whether the column should be indexed.

Implementations

impl ColumnDef

pub fn new(name: &str, col_type: ColumnType) -> Self

Creates a new column definition with sensible defaults.

pub fn nullable(self) -> Self

Marks the column as nullable.

pub fn default(self, val: Value) -> Self

Sets the default value for the column.

pub fn primary_key(self) -> Self

Marks the column as the primary key.

pub fn auto_increment(self) -> Self

Marks the column as auto-incrementing.

pub fn unique(self) -> Self

Marks the column as unique.

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.
