Implementations

impl PrimaryKeyDef

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

Creates a primary key named name, defaulting to an auto-incrementing i32.

pub fn i32(self) -> Self

Uses a 32-bit integer primary key (the default).

pub fn i64(self) -> Self

Uses a 64-bit integer primary key.

pub fn uuid(self) -> Self

Uses a UUID primary key. Disables auto-increment, since UUIDs are generated client-side rather than by the database sequence.

pub fn auto_increment(self) -> Self

Marks the primary key as auto-incrementing.

pub fn no_auto_increment(self) -> Self

Disables auto-increment — the caller is responsible for supplying the primary key value on insert.

Trait Implementations

impl Clone for PrimaryKeyDef

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PrimaryKeyDef

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

Formats the value using the given formatter.
