sourceยง

impl Default for ForeignKeyAction

sourceยง

sourceยง

impl From<&str> for ForeignKeyAction

sourceยง

fn from(action: &str) -> Self

Converts to this type from the input type.
sourceยง

impl PartialEq for ForeignKeyAction

sourceยง

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

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

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.
