Struct Through 

pub struct Through {
    pub table: TableName,
    pub left_key: ColumnName,
    pub right_key: ColumnName,
    pub filters: Option<Vec<Filter>>,
}

A junction table linking two sides of a many-to-many relation.

Fields

table: TableName

left_key: ColumnName

right_key: ColumnName

filters: Option<Vec<Filter>>

Conditions on the junction rows themselves (e.g. skip cancelled order lines), as opposed to the relation’s own filters on the target table.

Trait Implementations

impl Clone for Through

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Through

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Through

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for Through

Hashes filters only when non-empty, so a schema that never opts in keeps the content hash (and so the physical index) it had before the field existed.

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

Feeds this value into the given Hasher.

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

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Serialize for Through

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
