Struct ForeignKey 

pub struct ForeignKey {
    pub columns: Vec<String>,
    pub table: String,
    pub references: Vec<String>,
}

A foreign key: columns of one table that refer to columns of another.

Fields

columns: Vec<String>

This table’s columns; empty on a column’s own constraint, where the column is the one.

table: String

The table referred to.

references: Vec<String>

Its columns; empty when the source names only the table (its primary key).

Implementations

impl ForeignKey

pub fn to(table: impl Into<String>, column: impl Into<String>) -> Self

A column’s reference to table.column.
