Table schema representation.

It is used to define the structure of a database table.

Required Associated Types

type Record: TableRecord<Schema = Self>

The TableRecord type associated with this table schema; which is the data returned by a query.

type Insert: InsertRecord<Schema = Self>

The InsertRecord type associated with this table schema.

type Update: UpdateRecord<Schema = Self>

The UpdateRecord type associated with this table schema.

type ForeignFetcher: ForeignFetcher

The ForeignFetcher type associated with this table schema.

Required Methods

fn table_name() -> &'static str

Returns the name of the table.

fn columns() -> &'static [ColumnDef]

Returns the column definitions of the table.

fn primary_key() -> &'static str

Returns the name of the primary key column.

fn to_values(self) -> Vec<(ColumnDef, Value)>

Converts itself into a vector of column-value pairs.

Provided Methods

fn foreign_fetcher() -> Self::ForeignFetcher

Returns an instance of the ForeignFetcher for this table schema.

fn fingerprint() -> TableFingerprint

Returns the fingerprint of the table schema.

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.
