Struct ColumnDefinition 

pub struct ColumnDefinition {
    pub name: String,
    pub data_type: DataType,
    pub nullable: bool,
    pub default: Option<DefaultValue>,
    pub primary_key: bool,
    pub unique: bool,
    pub autoincrement: bool,
    pub references: Option<ForeignKeyRef>,
    pub check: Option<String>,
    pub collation: Option<String>,
}

A complete column definition for migrations.

Fields

name: String

Column name.

data_type: DataType

Data type.

nullable: bool

Whether the column is nullable.

default: Option<DefaultValue>

Default value.

primary_key: bool

Whether this is a primary key.

unique: bool

Whether this column is unique.

autoincrement: bool

Whether this column auto-increments.

references: Option<ForeignKeyRef>

Foreign key reference, if any.

check: Option<String>

Check constraint expression, if any.

collation: Option<String>

Collation for string columns.

Implementations

impl ColumnDefinition

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

Creates a new column definition.

Trait Implementations

impl Clone for ColumnDefinition

fn clone(&self) -> ColumnDefinition

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ColumnDefinition

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

Formats the value using the given formatter.

impl PartialEq for ColumnDefinition

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