Struct phile::sqir::RelationSide

pub struct RelationSide {
    pub entity: RcType,
    pub field: Option<String>,
    pub cardinality: Cardinality,
}

Represents one side of a relationship between two entities. A particular RelationSide always describes the relation from the point of view of one particular entity type.

Fields

entity: RcType

Pointer to the type which forms this side of the relationship.

field: Option<String>

Name of the field this side uses to refer to the other side.

cardinality: Cardinality

Number of instances of this entity that may correspond to an instance in the other entity.

Trait Implementations

impl Debug for RelationSide

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Clone for RelationSide

fn clone(&self) -> RelationSide

Returns a copy of the value.

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

impl Eq for RelationSide

impl PartialOrd for RelationSide

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

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl Ord for RelationSide

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

This method returns an Ordering between self and other.
