Struct ResourceFlags 

#[repr(transparent)]
pub struct ResourceFlags(pub c_int);

Create-or-take-over flags for registering a resource type.

Combine with |, e.g. ResourceFlags::CREATE | ResourceFlags::TAKEOVER. Passed to open_resource_type and friends, which report through their tried out-parameter which operation actually occurred.

Implementations

impl ResourceFlags

pub const CREATE: Self

Register the name as a new resource type.

Combine with ResourceFlags::TAKEOVER to accept either a fresh registration or a takeover of an existing one.

pub const TAKEOVER: Self

Take over an existing resource type during a code upgrade.

Lets the new library inherit a type registered by the version it replaces. Combine with ResourceFlags::CREATE to allow either.

Trait Implementations

impl BitOr for ResourceFlags

type Output = ResourceFlags

The resulting type after applying the | operator.

fn bitor(self, rhs: Self) -> Self

Performs the | operation.

impl Clone for ResourceFlags

fn clone(&self) -> ResourceFlags

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ResourceFlags

impl Eq for ResourceFlags

impl PartialEq for ResourceFlags

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