Struct ColumnReference 

#[non_exhaustive]
pub struct ColumnReference {
    pub referencing_column: String,
    pub referenced_column: String,
    /* private fields */
}

The pair of the foreign key column and primary key column.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

referencing_column: String

Required. The column that composes the foreign key.

referenced_column: String

Required. The column in the primary key that are referenced by the referencing_column.

Implementations

impl ColumnReference

pub fn new() -> Self

Creates a new default instance.

pub fn set_referencing_column<T: Into<String>>(self, v: T) -> Self

Sets the value of referencing_column.

Example

let x = ColumnReference::new().set_referencing_column("example");

pub fn set_referenced_column<T: Into<String>>(self, v: T) -> Self

Sets the value of referenced_column.

Example

let x = ColumnReference::new().set_referenced_column("example");
