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, __A> Decode<'__de, Binary, __A> for Flags

where __A: Allocator,

const IS_BITWISE_DECODE: bool = false

Whether the type is packed. Packed types can be bitwise copied if the representation of the serialization format is identical to the memory layout of the type.

fn decode<T0>(_1: T0) -> Result<Self, <T0 as Decoder<'__de>>::Error>

where T0: Decoder<'__de, Mode = Binary, Allocator = __A>,

Decode the current value.

impl<'__de, __A> Decode<'__de, Text, __A> for Flags

where __A: Allocator,

const IS_BITWISE_DECODE: bool = false

Whether the type is packed. Packed types can be bitwise copied if the representation of the serialization format is identical to the memory layout of the type.

fn decode<T0>(_1: T0) -> Result<Self, <T0 as Decoder<'__de>>::Error>

where T0: Decoder<'__de, Mode = Text, Allocator = __A>,

Decode the current value.

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

const IS_BITWISE_ENCODE: bool = false

Whether the type is packed. Packed types can be bitwise copied if the representation of the serialization format is identical to the memory layout of the type.

type Encode = Flags

The underlying type being encoded.

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

where T0: Encoder<Mode = Binary>,

Encode the given output.

fn size_hint(&self) -> Option<usize>

The number of fields in the type.

fn as_encode(&self) -> &Self::Encode

Coerce into the underlying value being encoded.

impl Encode<Text> for Flags

const IS_BITWISE_ENCODE: bool = false

Whether the type is packed. Packed types can be bitwise copied if the representation of the serialization format is identical to the memory layout of the type.

type Encode = Flags

The underlying type being encoded.

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

where T0: Encoder<Mode = Text>,

Encode the given output.

fn size_hint(&self) -> Option<usize>

The number of fields in the type.

fn as_encode(&self) -> &Self::Encode

Coerce into the underlying value being encoded.

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
