RecordLoad

Struct RecordLoad 

Source
pub struct RecordLoad {
    pub common_fields: Vec<(String, EpicsValue)>,
    pub info_tags: Vec<(String, String)>,
}
Expand description

What a .db definition carries into the creation sink alongside the record itself: the dbCommon fields db_loader::apply_fields could not route to the record’s own field_list, and the record’s info(...) tags.

It exists so that PvDatabase::add_loaded_record receives a record’s COMPLETE loaded state in one call. A caller cannot add the record and then apply its .db fields, because the sink runs C’s iocInit passes — whose result depends on those fields — before the record is reachable at all.

Fields§

§common_fields: Vec<(String, EpicsValue)>

dbCommon fields, in .db file order (a later field(UDF,…) wins).

§info_tags: Vec<(String, String)>

info(key, "value") tags.

Implementations§

Source§

impl RecordLoad

Source

pub fn from_common_fields(common_fields: Vec<(String, EpicsValue)>) -> Self
