A domain type mapped to a store table.

Required Methods

fn table() -> Table

Table this model maps to.

fn fields() -> Vec<Field>

Field definitions for this model’s table.

fn write(&self, w: &mut dyn Writer)

Write all non-id values to the given writer.

fn read(r: &mut dyn Reader) -> Result<Self, StoreError>

Read a new value from the given reader.

fn write_id(&self, w: &mut dyn Writer)

Write just the id values to the given writer.

fn read_id(&mut self, r: &mut dyn Reader) -> Result<(), StoreError>

Read just the id values from the given reader.

Provided Methods

fn columns() -> Vec<Name>

Names of the plain cell columns.

fn search() -> Vec<Name>

Names of the text columns, used for free-text search.

fn readonly() -> Vec<Name>

Names of the columns the UI shows as read-only.

fn actions() -> Vec<Action>

Actions the UI offers, defaulting to wipe.

fn schema() -> Schema

Schema derived from this model’s table and fields.

fn spec() -> Schema

Full schema including any overriding rules.

fn row(&self) -> Vec<Value>

Cell values of this model in field order.

fn id(&self) -> Value

Key value of this model.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
