Struct ColumnDef 

pub struct ColumnDef {
    pub name: &'static str,
    pub sql_type: SqlType,
    pub primary_key: bool,
    pub auto: bool,
    pub nullable: bool,
    pub foreign_key: Option<ForeignKeyDef>,
    pub default: Option<ColumnDefault>,
}

The compile-time description of a single model column.

Fields

name: &'static str

The column name in the database.

sql_type: SqlType

The abstract SQL type of the column.

primary_key: bool

Whether the column is (part of) the primary key.

auto: bool

Whether the database assigns the value automatically (auto-increment).

nullable: bool

Whether the column accepts NULL (the Rust field is an Option).

foreign_key: Option<ForeignKeyDef>

A foreign key reference, if the column points at another table.

default: Option<ColumnDefault>

A database-side default; when set, the column is omitted from INSERT.

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 Copy for ColumnDef

impl Debug for ColumnDef

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

Formats the value using the given formatter.

impl Eq for ColumnDef

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.
