Implementations

impl PValue

pub fn zero(ptype: PType) -> PValue

Creates a zero value for the given primitive type.

pub fn ptype(&self) -> PType

Returns the primitive type of this value.

pub fn is_instance_of(&self, ptype: &PType) -> bool

Returns true if this value is of the given primitive type.

pub fn cast<T: NativePType>(&self) -> T

Converts this value to a specific native primitive type.

Panics if the conversion is not supported or would overflow.

Panics

Panics if the target type has a different byte width than this value.
