Enum RefreshPolicy 

pub enum RefreshPolicy {
    Manual,
    OnLoad,
    Interval {
        secs: u64,
    },
}

When an external-sourced measure (SQL or external-function) should refresh.

Variants

Manual

Only when explicitly asked (the safe default).

OnLoad

Whenever the model is loaded/opened by a tool that honors the policy.

Interval

At most every secs seconds (advisory; the honoring tool tracks time).

Fields

secs: u64
