Struct Junction 

pub struct Junction {
    pub table: QualifiedIdentifier,
    pub constraint1: CompactString,
    pub constraint2: CompactString,
    pub cols_source: SmallVec<[(CompactString, CompactString); 2]>,
    pub cols_target: SmallVec<[(CompactString, CompactString); 2]>,
}

Junction table for many-to-many relationships

Represents the intermediate table that connects two tables in an M2M relationship.

Fields

table: QualifiedIdentifier

The junction table

constraint1: CompactString

FK constraint from junction to source table

constraint2: CompactString

FK constraint from junction to target table

cols_source: SmallVec<[(CompactString, CompactString); 2]>

Column mappings from junction to source: (junction_col, source_col)

cols_target: SmallVec<[(CompactString, CompactString); 2]>

Column mappings from junction to target: (junction_col, target_col)

Implementations

impl Junction

pub fn junction_columns(&self) -> impl Iterator<Item = &str>

Get all junction table columns used in the relationship

pub fn source_columns(&self) -> impl Iterator<Item = &str>
