Struct TypeInstance 

pub struct TypeInstance {
    pub type_tag: Arc<str>,
    pub fields: MapValue,
    pub mutable: Option<GcPtr<Atom>>,
}

A record or reify instance. type_tag identifies the concrete type; fields holds the key/value pairs (keyword → value).

Fields

type_tag: Arc<str>

fields: MapValue

mutable: Option<GcPtr<Atom>>

Mutable deftype fields (^:unsynchronized-mutable / ^:volatile-mutable), held in an interior-mutable cell — an Atom over a keyword→value map — so set! can update them in place. None for defrecord, reify, and immutable deftypes. Instances are !Send, so one shared cell needs no stronger volatility than an Atom.
