Struct ColumnDef 

pub struct ColumnDef {
    pub name: ColumnName,
    pub data_type: DataType,
    pub nullable: bool,
}

Definition of a table column.

Fields

name: ColumnName

Column name.

data_type: DataType

Column data type.

nullable: bool

Whether the column can contain NULL values.

Implementations

impl ColumnDef

pub fn new(name: impl Into<ColumnName>, data_type: DataType) -> ColumnDef

Creates a new column definition.

pub fn not_null(self) -> ColumnDef

Makes this column non-nullable.

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<(), Error>

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.
