Trait Model

pub trait Model {
    // Required methods
    fn table_name() -> &'static str;
    fn columns() -> &'static [Column<'static>];
    fn count_columns() -> usize;
    fn get_id(&self) -> i64;
    fn id_column() -> Column<'static>;
    fn column_value(
        &self,
        column: &'static Column<'static>,
    ) -> Option<Box<dyn ToSql>>;
    fn parse_rows(
        rows: Rows<'_>,
        offset: usize,
        joins: &Vec<String>,
    ) -> Vec<Self>
       where Self: Sized;
    fn parse_row(row: &Row<'_>, offset: usize, joins: &Vec<String>) -> Self
       where Self: Sized;
}

A trait that needs to be implemented for all models that are used with sequelite.

This trait is hard to implement manually, so it is automatically implemented for every struct that derives Model.

Note

This trait is not meant to be implemented manually.

Required Methods

fn table_name() -> &'static str

fn columns() -> &'static [Column<'static>]

fn count_columns() -> usize

fn get_id(&self) -> i64

fn id_column() -> Column<'static>

fn column_value( &self, column: &'static Column<'static>, ) -> Option<Box<dyn ToSql>>

fn parse_rows(rows: Rows<'_>, offset: usize, joins: &Vec<String>) -> Vec<Self>

where Self: Sized,

fn parse_row(row: &Row<'_>, offset: usize, joins: &Vec<String>) -> Self

where Self: Sized,

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
