Struct ProjectionRelationship 

pub struct ProjectionRelationship { /* private fields */ }

Provenance for a mutation of a relationship-owned row.

Implementations

impl ProjectionRelationship

pub fn try_new( source_model: impl Into<String>, relationship: impl Into<String>, target_model: impl Into<String>, ) -> Result<Self, ProjectionProgramError>

Construct stable relationship provenance.

Errors

Rejects empty model and relationship names.

pub fn source_model(&self) -> &str

Return the relationship source model.

pub fn relationship(&self) -> &str

Return the stable relationship name.

pub fn target_model(&self) -> &str

Return the relationship target model.

Trait Implementations

impl Clone for ProjectionRelationship

fn clone(&self) -> ProjectionRelationship

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ProjectionRelationship

impl Eq for ProjectionRelationship

impl Hash for ProjectionRelationship

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

Feeds this value into the given Hasher.

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

impl Ord for ProjectionRelationship

fn cmp(&self, other: &ProjectionRelationship) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

fn clamp_to<R>(self, range: R) -> Self

where Self: Sized, R: ClampBounds<Self>,

🔬This is a nightly-only experimental API. (clamp_to)

Restrict a value to a certain range.

impl PartialEq for ProjectionRelationship

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for ProjectionRelationship

fn partial_cmp(&self, other: &ProjectionRelationship) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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