Enum DiagnosticArg 

pub enum DiagnosticArg {
    Type(TypeId),
    Symbol(SymbolId),
    Atom(Atom),
    String(Arc<str>),
    Number(usize),
}

Argument for a diagnostic message template.

Instead of eagerly formatting types to strings, we store the raw data (TypeId, SymbolId, etc.) and only format when rendering.

Variants

Type(TypeId)

A type reference (will be formatted via TypeFormatter)

Symbol(SymbolId)

A symbol reference (will be looked up by name)

Atom(Atom)

An interned string

String(Arc<str>)

A plain string

Number(usize)

A number
