Methods

impl DbFlags

fn empty() -> DbFlags

Returns an empty set of flags.

fn all() -> DbFlags

Returns the set containing all flags.

fn bits(&self) -> c_uint

Returns the raw value of the flags currently stored.

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.

fn from_bits_truncate(bits: c_uint) -> DbFlags

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: DbFlags) -> bool

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

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

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

fn insert(&mut self, other: DbFlags)

Inserts the specified flags in-place.

fn remove(&mut self, other: DbFlags)

Removes the specified flags in-place.

fn toggle(&mut self, other: DbFlags)

Toggles the specified flags in-place.

Trait Implementations

impl PartialOrd for DbFlags

fn partial_cmp(&self, __arg_0: &DbFlags) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, __arg_0: &DbFlags) -> bool

This method tests less than (for self and other) and is used by the < operator.
