Required methods

fn get_table_name() -> &'static str

Returns the name of the table.

fn get_primary_key() -> &'static str

Returns the Postgres name of the primary key.

fn get_primary_key_value(&self) -> Self::PK where
    Self::PK: ToSqlItem + Sized + Sync, 

Returns the value of the primary key.

fn get_fields() -> &'static str

The fields that contain the data of the table. The primary key is excluded from this list.

fn get_all_fields() -> &'static str

Returns a comma separated list with the Postgres names of all fields.

fn get_values_of_all_fields(&self) -> Vec<&(dyn ToSqlItem + Sync)>

Returns a vector of references to all values of the implemented struct.

fn get_query_params(&self) -> Vec<&(dyn ToSqlItem + Sync)>

The method that implements converting the fields into a array of items that implement the ToSql trait of rust_postgres.

fn get_prepared_arguments_list() -> &'static str

Returns the formatted prepared statement list.

Example return value: $1, $2

fn get_prepared_arguments_list_with_types() -> &'static str

Returns the formatted prepared statement list with Postgres types.

Example return value: $1::INT, $2::VARCHAR

fn get_argument_count() -> usize

Returns the amount of fields excluding the primary key.
