Struct Rule 

pub struct Rule {
    pub name: String,
    pub prop_id: String,
    pub out_exp: bool,
    pub exprs: Vec<RuleExpr>,
    pub pv_names: Vec<String>,
    pub check_connections: bool,
}

A rule: sets property prop_id from the first expression that holds.

Fields

name: String

prop_id: String

out_exp: bool

When true the expression’s value is the property value (out_exp).

exprs: Vec<RuleExpr>

pv_names: Vec<String>

check_connections: bool

Whether to wait for every PV to connect before evaluating. BOY evaluates regardless, reading a disconnected PV as INVALID, and an .opi rule carries check_connections="false" to say so.
