Struct Flags

pub struct Flags(/* private fields */);

Format specification flags.

Implementations

impl Flags

pub fn is_empty(self) -> bool

Check if the set of flags is empty.

pub fn into_u32(self) -> u32

Get the flags as a number. This representation is not guaranteed to be stable.

pub fn set(&mut self, flag: Flag)

Set the given flag.

pub fn test(&self, flag: Flag) -> bool

Test the given flag.

Trait Implementations

impl Clone for Flags

fn clone(&self) -> Flags

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Flags

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Decode<'de, Binary> for Flags

fn decode<T0>(_0: &T0::Cx, _1: T0) -> Result<Self, <T0::Cx as Context>::Error>

where T0: Decoder<'de, Mode = Binary>,

Decode the given input.

impl<'de> Decode<'de, Text> for Flags

fn decode<T0>(_0: &T0::Cx, _1: T0) -> Result<Self, <T0::Cx as Context>::Error>

where T0: Decoder<'de, Mode = Text>,

Decode the given input.

impl Default for Flags

fn default() -> Flags

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Flags

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Encode<Binary> for Flags

fn encode<T0>( &self, _1: &T0::Cx, _0: T0, ) -> Result<<T0 as Encoder>::Ok, <T0 as Encoder>::Error>

where T0: Encoder<Mode = Binary>,

Encode the given output.

impl Encode<Text> for Flags

fn encode<T0>( &self, _1: &T0::Cx, _0: T0, ) -> Result<<T0 as Encoder>::Ok, <T0 as Encoder>::Error>

where T0: Encoder<Mode = Text>,

Encode the given output.

impl From<u32> for Flags

fn from(flags: u32) -> Self

Converts to this type from the input type.

impl PartialEq for Flags

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

impl Serialize for Flags

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TryClone for Flags

fn try_clone(&self) -> Result<Self>

Try to clone the current value, raising an allocation error if it’s unsuccessful.

fn try_clone_from(&mut self, source: &Self) -> Result<(), Error>

Performs copy-assignment from source.

impl Copy for Flags

impl Eq for Flags

impl StructuralPartialEq for Flags
