Enum FieldMapping 

pub enum FieldMapping {
    Scalar,
    Plain,
    Meta,
    Any,
    Proc,
}

How a member PV’s value is mapped into the group structure.

Variants

Scalar

NTScalar/NTScalarArray with full metadata (alarm, timestamp, display, control).

Plain

Value only, no metadata.

Meta

Alarm + timestamp only, no value transfer.

Any

Variant-union wrapping (pass-through).

Proc

Process-only: put triggers record processing, no value transfer.

Trait Implementations

impl Clone for FieldMapping

fn clone(&self) -> FieldMapping

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for FieldMapping

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for FieldMapping

fn eq(&self, other: &FieldMapping) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
