Type Alias Meta 

pub type Meta = Map<String, Value>;

Available on crate feature unstable_protocol_v2 only.

Value attached to a given ACP type on the _meta field.

The _meta property is reserved by ACP to allow clients and agents to attach additional metadata to their interactions. It is an object with string keys; receivers treat any other value as omitted. Implementations MUST NOT make assumptions about values at these keys.

See protocol docs: Extensibility
