Enum RelationType 

pub enum RelationType {
    OneToOne,
    OneToMany,
    ManyToOne,
    ManyToMany,
}

Type of relation between models.

Variants

OneToOne

One-to-one relation (e.g., User has one Profile).

OneToMany

One-to-many relation (e.g., User has many Posts).

ManyToOne

Many-to-one relation (e.g., Post belongs to User).

ManyToMany

Many-to-many relation (e.g., Post has many Tags).

Implementations

impl RelationType

pub fn is_many(&self) -> bool

Check if this relation returns multiple records.

pub fn is_one(&self) -> bool

Check if this relation returns a single record.

Trait Implementations

impl Clone for RelationType

fn clone(&self) -> RelationType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RelationType

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

Formats the value using the given formatter.

impl Hash for RelationType

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for RelationType

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