Methods

impl DatabaseFlags

fn empty() -> DatabaseFlags

Returns an empty set of flags.

fn all() -> DatabaseFlags

Returns the set containing all flags.

fn bits(&self) -> u32

Returns the raw value of the flags currently stored.

fn from_bits(bits: u32) -> Option<DatabaseFlags>

Convert from underlying bit representation, unless that representation contains bits that do not correspond to a flag.

fn from_bits_truncate(bits: u32) -> DatabaseFlags

Convert from underlying bit representation, dropping any bits that do not correspond to flags.

fn is_empty(&self) -> bool

Returns true if no flags are currently stored.

fn is_all(&self) -> bool

Returns true if all flags are currently set.

fn intersects(&self, other: DatabaseFlags) -> bool

Returns true if there are flags common to both self and other.

fn contains(&self, other: DatabaseFlags) -> bool

Returns true all of the flags in other are contained within self.

fn insert(&mut self, other: DatabaseFlags)

Inserts the specified flags in-place.

fn remove(&mut self, other: DatabaseFlags)

Removes the specified flags in-place.

fn toggle(&mut self, other: DatabaseFlags)

Toggles the specified flags in-place.

fn set(&mut self, other: DatabaseFlags, value: bool)

Inserts or removes the specified flags depending on the passed value.
