Implementations

impl PrimaryKeyIr

pub fn fields(&self) -> Vec<&str>

Returns the field names that form the primary key.

pub fn is_single(&self) -> bool

Returns true if this is a single-field primary key.

pub fn is_composite(&self) -> bool

Returns true if this is a composite primary key.

Trait Implementations

impl Clone for PrimaryKeyIr

fn clone(&self) -> PrimaryKeyIr

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PrimaryKeyIr

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

Formats the value using the given formatter.

impl PartialEq for PrimaryKeyIr

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