Enum RoutineBody 

pub enum RoutineBody {
    Expression(String),
    Query(String),
    Statements(Vec<String>),
    Block(String),
}

The routine’s body, in the shape Razeri composed it.

Variants

Expression(String)

A single expression the function’s value is.

Query(String)

A query whose rows the function returns.

Statements(Vec<String>)

Statements, in order, each as Razeri composed it — which means a statement that needs a ; already carries one, and a block statement carries the ; its own grammar puts inside it.

How they are separated, and how the block around them is opened and closed, is still the engine’s business. An engine that ends a statement some other way reads the last character rather than assuming: a ; stripped off END IF; takes a keyword’s punctuation, not a separator.

Block(String)

A procedural block the design supplied already framed. Emit it as it stands, inside whatever this engine wraps a body in.
