Implementations

impl ReferentialAction

pub fn to_prax(&self) -> &'static str

Convert to Prax schema string.

pub fn from_str(s: &str) -> Self

Parse from database string.

Trait Implementations

impl Clone for ReferentialAction

fn clone(&self) -> ReferentialAction

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ReferentialAction

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

Formats the value using the given formatter.

impl Default for ReferentialAction

fn default() -> ReferentialAction

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ReferentialAction

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ReferentialAction

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

impl Serialize for ReferentialAction

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
