Enum ExpressionKind

pub enum ExpressionKind {
    Boolean,
    Instance,
}

The type of Expressions, which is either a boolean expression or an instance expression.

Note that strings and integers are seen as instances.

Variants

Boolean

Boolean expressions evaluate to true or false.

Instance

Instance expressions evaluate to zero or more instances of a particular type.

Trait Implementations

impl Clone for ExpressionKind

fn clone(&self) -> ExpressionKind

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ExpressionKind

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

Formats the value using the given formatter.

impl EnumDebug for ExpressionKind

fn type_name() -> &'static str

Returns the static name of the type used for EnumDebug-printing.

fn variant_names() -> &'static [&'static str]

Returns all variants in the trait as a list of names.

fn variant_name(&self) -> &'static str

Returns the static name of the variant.

fn variant(&self) -> EnumDebugFormatter<'_, Self>

Returns a formatter for this enum that writes its variant name.

fn variants() -> Copied<Iter<'static, &'static str>>

Returns an iterator over all variants in this enum.

impl Hash for ExpressionKind

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for ExpressionKind

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