Returns the raw value of the flags currently stored.
pub fn from_bits(bits: c_uint) -> Option<EnvFlags>
pub fn from_bits(bits: c_uint) -> Option<EnvFlags>

Returns true
if no flags are currently stored.

pub fn is_all(&self) -> bool
Returns true
if all flags are currently set.
pub fn intersects(&self, other: EnvFlags) -> bool
pub fn intersects(&self, other: EnvFlags) -> bool
