Trait Implementations

impl Clone for RelationDefinition

fn clone(&self) -> RelationDefinition

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RelationDefinition

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

Formats the value using the given formatter.

impl Default for RelationDefinition

fn default() -> RelationDefinition

Returns the “default value” for a type.

impl Display for RelationDefinition

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

Formats the value using the given formatter.

impl<'a> FetchTarget<'a, RelationDefinition> for RelationDefinitionTarget

fn fetch_values( &self, spec: &'a Specification, ) -> Result<&'a [RelationDefinition], TargetError<Self>>

Fetch the map reference containing the targeted item.

fn fetch_values_mut( &self, spec: &'a mut Specification, ) -> Result<&'a mut [RelationDefinition], TargetError<Self>>

Fetch the mutable map reference containing the targeted item.

fn index(&self) -> usize

The index to access in the selected map.

fn fetch(&self, spec: &'a Specification) -> Result<&'a V, TargetError<Self>>

Fetch a reference to the target from the specification.

fn fetch_mut( &self, spec: &'a mut Specification, ) -> Result<&'a mut V, TargetError<Self>>

Fetch a mutable reference to the target from the specification.

impl PartialEq for RelationDefinition

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