Struct winsafe::co::VT

pub struct VT(/* private fields */);

Available on crate features kernel and oleaut only.

VARENUM enumeration (u16).

This is a bitflag constant, which implements the NativeBitflag trait.

Implementations

impl VT

pub const unsafe fn from_raw(v: u16) -> Self

Constructs a new object by wrapping the given integer value.

Safety

Be sure the given value is meaningful for the actual type.

pub const fn raw(&self) -> u16

Returns the primitive integer underlying value.

This method is similar to Into, but it is const, therefore it can be used in const contexts.
