Struct ColumnDef 

pub struct ColumnDef {
    pub name: Ident,
    pub ty: ColumnType,
    pub not_null: bool,
    pub primary_key: bool,
    pub auto_increment: bool,
    pub unique: bool,
    pub default: Option<Expr>,
    pub check: Option<Expr>,
}

A column definition.

Fields

name: Ident

The column name.

ty: ColumnType

The logical type.

not_null: bool

Whether NOT NULL is set.

primary_key: bool

Whether the column is a single-column PRIMARY KEY.

auto_increment: bool

Whether AUTOINCREMENT is set; requires an INTEGER PRIMARY KEY.

unique: bool

Whether UNIQUE is set.

default: Option<Expr>

The DEFAULT expr, inlined as a literal when rendered.

check: Option<Expr>

The CHECK (expr) constraint.
