Enum Shown 

pub enum Shown<'a> {
    Null,
    Bool(bool),
    Integer(i64),
    Float(f64),
    Number(&'a Number),
    Text(&'a str),
    Uuid(Uuid),
    Instant(Instant),
    Formatted(&'a dyn Display),
    List(&'a dyn Items),
    Record(&'a dyn Fields),
}

What a screen reads of a value: borrowed from it, so reading allocates nothing.

Variants

Null

Bool(bool)

Integer(i64)

Float(f64)

Number(&'a Number)

Text(&'a str)

Uuid(Uuid)

Hex digits and hyphens only, so a page writes it without escaping or percent-encoding.

Instant(Instant)

Typed, so a screen tells it from text written like one.

Formatted(&'a dyn Display)

List(&'a dyn Items)

Record(&'a dyn Fields)
