Expand description

Definition of a Table used to generate the SQL schema

Created by the #[derive(Table)] proc-macro.

Fields§

§name: &'static str

Name of the table: #[derive(Table)] uses the lowercase name of the struct

§primary_key: &'static [&'static str]

Names of the Columns that make up the values of the primary #[key]

This is empty if the Table has no primary key.

§values: Values

Definitions and names for all constituent Values

§key_values: Values

Definitions and names for all (if any) primary key Values

§other_values: Values

Definitions and names for all Values that are not (part of) the primary key.

This could be empty (if all [Value']s are part of the primary key), or it could be equal to values`.

§constraints: &'static [Constraint]

List of Table-level Constraints
