var.opDispatch

var opDispatch(string name)() ref @safe

Dynamic field access for map values via D's opDispatch.

Mutable overload: routes unknown identifiers to map entries, returning ref var and inserting a default when missing. If the current value is Type.NULL, it is promoted to Type.OBJECT on first write. If the current value is neither NULL nor OBJECT, a VarTypeException is thrown.

Error messages include the field name being accessed for easier debugging.

Parameters

name The field name to access (compile-time string parameter).

Returns

A reference to the value at the given field, creating it if necessary.

See Also

getField for safe access that returns a default instead of asserting.

const(var) opDispatch(string name)() ref const @safe

Const overload of opDispatch for read-only access (no insertion).

Asserts with a descriptive message if:

The value is not a map (includes the actual type in the message).
The requested key is missing (includes the key name in the message).
Parameters
name The field name to access (compile-time string parameter).

Returns
A const reference to the value at the given field.
