Struct TableMap 

pub struct TableMap { /* private fields */ }

How an entity lands on a table.

Implementations

impl TableMap

pub fn new(table: impl Into<String>) -> Self

On this table, with each field in a column of its name.

pub fn column(self, field: impl Into<String>, column: impl Into<String>) -> Self

This field is in a column of another name.

pub fn computed(self, field: impl Into<String>, sql: impl Into<String>) -> Self

This field is not stored: the database works it out with this SQL expression over the table, which is trusted as written and never comes from people.

pub fn before_save(self, hook: impl Fn(&mut Object) + 'static) -> Self

Runs on a record just before it is written, to fit what the table asks for.

pub fn after_load(self, hook: impl Fn(&mut Object) + 'static) -> Self

Runs on a record just after it is read.
