Implementations

impl PrimitiveValType

pub fn is_subtype_of(a: PrimitiveValType, b: PrimitiveValType) -> bool

Determines if primitive value type a is a subtype of b.

Trait Implementations

impl Clone for PrimitiveValType

fn clone(&self) -> PrimitiveValType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PrimitiveValType

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

Formats the value using the given formatter.

impl Display for PrimitiveValType

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

Formats the value using the given formatter.

impl From<PrimitiveValType> for PrimitiveValType

fn from(ty: PrimitiveValType) -> PrimitiveValType

Converts to this type from the input type.

impl PartialEq for PrimitiveValType

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