Enum VarKind 

pub enum VarKind {
    Plain,
    Var,
    Varip,
}

How a variable declaration behaves across bars.

Variants

Plain

x = expr — the initializer is re-evaluated on every bar.

Var

var x = expr — the initializer runs once; the value persists across bars.

Varip

varip x = expr — like Var, but also updates intrabar in realtime.

Implementations

impl VarKind

pub fn is_persistent(self) -> bool

var/varip: initialize once and retain the value across bars.
