Enum PatternValuePlace 

pub enum PatternValuePlace {
    Placeholder,
    Variable(Variable),
    EntidOrInteger(i64),
    IdentOrKeyword(ValueRc<Keyword>),
    Constant(NonIntegerConstant),
}

The v part of a pattern can be much broader: it can represent integers that aren’t entity IDs (particularly negative integers), strings, and all the rest. We group those under Constant.

Variants

Placeholder

Variable(Variable)

EntidOrInteger(i64)

IdentOrKeyword(ValueRc<Keyword>)

Constant(NonIntegerConstant)

Trait Implementations

impl Clone for PatternValuePlace

fn clone(&self) -> PatternValuePlace

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PatternValuePlace

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

Formats the value using the given formatter.

impl Display for PatternValuePlace

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

Formats the value using the given formatter.

impl Eq for PatternValuePlace

impl From<Keyword> for PatternValuePlace

fn from(value: Keyword) -> Self

Converts to this type from the input type.

impl From<Rc<Keyword>> for PatternValuePlace

fn from(value: Rc<Keyword>) -> Self

Converts to this type from the input type.

impl FromValue<PatternValuePlace> for PatternValuePlace

fn from_value(v: &ValueAndSpan) -> Option<PatternValuePlace>

impl PartialEq for PatternValuePlace

fn eq(&self, other: &PatternValuePlace) -> 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.
