Enum stam::SelectionQualifier

pub enum SelectionQualifier {
    Normal,
    Metadata,
}

This is determines whether a query Constraint is applied normally or with a particular altered meaning.

Variants

Normal

Normal behaviour, no changes.

Metadata

This corresponds to the TARGET or METADATA keyword in STAMQL. It indicates that the item in the constrain is an explicit annotation TARGET. It causes the logic flow to go over methods like annotations_as_metadata() instead of annotations()

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

Performs copy-assignment from source.

impl Debug for SelectionQualifier

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

Formats the value using the given formatter.

impl Default for SelectionQualifier

fn default() -> Self

impl PartialEq for SelectionQualifier

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

This method tests for self and other values to be equal, and is used by ==.

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

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