Struct Schema 

pub struct Schema { /* private fields */ }

A Schema (or Layout, hence the crate name) encompasses one or more Tables. Can be converted into an SQL Statement via the SQLStatement Methods. It is an Error for the Schema to be empty ([Error::SchemaWithoutTables]).

Implementations

impl Schema

pub fn new() -> Self

pub fn add_table(self, new_table: Table) -> Self

pub fn add_view(self, new_view: View) -> Self

Trait Implementations

impl Clone for Schema

fn clone(&self) -> Schema

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Schema

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Schema

fn default() -> Schema

Returns the “default value” for a type.

impl PartialEq for Schema

fn eq(&self, other: &Schema) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl SQLStatement for Schema

fn len(&mut self, transaction: bool, if_exists: bool) -> Result<usize>

Calculates the exact length of the statement as it is currently configured. Any change to the configuration invalidates previously calculated lengths. Parameters are the same as in SQLStatement::build.

fn build(&mut self, transaction: bool, if_exists: bool) -> Result<String>

Builds the SQL Statement as a String.
