Trait TangoElement 

pub trait TangoElement: Element {
    const ATTR_KIND: AttrDataKind;
    const CMD_SCALAR_KIND: Option<CommandDataKind>;
    const CMD_ARRAY_KIND: Option<CommandDataKind>;

    // Required methods
    fn wrap(format: ValueFormat<Self>) -> Value;
    fn unwrap(data: Value) -> Result<ValueFormat<Self>, Value>;
    fn unwrap_ref(data: &Value) -> Option<&ValueFormat<Self>>;
}

An element type Tango has: which variant of Value holds it, and what kinds it is advertised as, see AttrData and CommandData.

Required Associated Constants

const ATTR_KIND: AttrDataKind

The kind of an attribute of such values.

const CMD_SCALAR_KIND: Option<CommandDataKind>

The kind of a command argument of one such value, absent if none can be.

const CMD_ARRAY_KIND: Option<CommandDataKind>

The kind of a command argument of an array of such values, absent if none can be.

Required Methods

fn wrap(format: ValueFormat<Self>) -> Value

fn unwrap(data: Value) -> Result<ValueFormat<Self>, Value>

fn unwrap_ref(data: &Value) -> Option<&ValueFormat<Self>>

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
