Enum psl::datamodel_connector::RelationMode

#[repr(u8)]
pub enum RelationMode {
    ForeignKeys = 1,
    Prisma = 2,
}

Defines the part of the stack where referential actions are handled.

Variants

ForeignKeys = 1

Enforced in the database. Needs support from the underlying database server.

Prisma = 2

Enforced in Prisma. Slower, but for databases that do not support foreign keys.

Implementations

impl RelationMode

pub fn allowed_emulated_referential_actions_default( ) -> BitFlags<ReferentialAction>

pub fn is_prisma(&self) -> bool

pub fn uses_foreign_keys(&self) -> bool

True, if integrity is in database foreign keys

Trait Implementations

impl BitAnd for RelationMode

type Output = BitFlags<RelationMode>

The resulting type after applying the & operator.

fn bitand(self, other: RelationMode) -> <RelationMode as BitAnd>::Output

Performs the & operation.

impl BitFlag for RelationMode

fn empty() -> BitFlags<Self>

Create a BitFlags with no flags set (in other words, with a value of 0).

fn all() -> BitFlags<Self>

Create a BitFlags with all flags set.

impl BitOr for RelationMode

type Output = BitFlags<RelationMode>

The resulting type after applying the | operator.

fn bitor(self, other: RelationMode) -> <RelationMode as BitOr>::Output

Performs the | operation.

impl BitXor for RelationMode

type Output = BitFlags<RelationMode>

The resulting type after applying the ^ operator.

fn bitxor(self, other: RelationMode) -> <RelationMode as BitXor>::Output

Performs the ^ operation.

impl Clone for RelationMode

fn clone(&self) -> RelationMode

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for RelationMode

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

Formats the value using the given formatter.

impl Default for RelationMode

fn default() -> RelationMode

Returns the “default value” for a type.

impl Display for RelationMode

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

Formats the value using the given formatter.

impl Not for RelationMode

type Output = BitFlags<RelationMode>

The resulting type after applying the ! operator.

fn not(self) -> <RelationMode as Not>::Output

Performs the unary ! operation.

impl PartialEq for RelationMode

fn eq(&self, other: &RelationMode) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Copy for RelationMode

impl StructuralPartialEq for RelationMode
