Implementations
sourceimpl DbFlags
impl DbFlags
sourcepub fn from_bits(bits: c_uint) -> Option<DbFlags>
pub fn from_bits(bits: c_uint) -> Option<DbFlags>
Convert from underlying bit representation, unless that representation contains bits that do not correspond to a flag.
sourcepub fn from_bits_truncate(bits: c_uint) -> DbFlags
pub fn from_bits_truncate(bits: c_uint) -> DbFlags
Convert from underlying bit representation, dropping any bits that do not correspond to flags.
sourcepub fn intersects(&self, other: DbFlags) -> bool
pub fn intersects(&self, other: DbFlags) -> bool
Returns true
if there are flags common to both self
and other
.
