Struct ShapeFlags 

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

Bit flags for common shape-level attributes.

These provide O(1) access to frequently-checked boolean attributes, avoiding the O(n) linear scan through the attributes slice.

Implementations

impl ShapeFlags

pub const UNTAGGED: ShapeFlags

Enum is untagged (no discriminant in serialized form). Set by #[facet(untagged)].

pub const NUMERIC: ShapeFlags

Serializes/Deserializers enum to/from integer based on variant discriminant, Set by #[facet(is_numeric)].

pub const POD: ShapeFlags

Plain Old Data - type has no invariants and any combination of valid field values produces a valid instance.

This enables safe mutation through reflection (poke operations). Set by #[facet(pod)].

pub const METADATA_CONTAINER: ShapeFlags

Metadata container - serializes transparently through the non-metadata field while preserving metadata fields for formats that support them.

Set by #[facet(metadata_container)].

pub const fn empty() -> ShapeFlags

An empty set of flags.

pub const fn is_empty(self) -> bool

Returns true if no flags are set.

pub const fn contains(self, other: ShapeFlags) -> bool

Returns true if all flags in other are contained in self.

pub const fn insert(&mut self, other: ShapeFlags)

Inserts the flags in other into self.

pub const fn remove(&mut self, other: ShapeFlags)

Removes the flags in other from self.

pub const fn union(self, other: ShapeFlags) -> ShapeFlags

Returns the union of self and other.

pub const fn intersection(self, other: ShapeFlags) -> ShapeFlags

Returns the intersection of self and other.

pub const fn bits(self) -> u16

Returns the raw bits.

pub const fn from_bits_retain(bits: u16) -> ShapeFlags

Creates from raw bits (unchecked).

Performs the & operation.

impl BitAndAssign for ShapeFlags

fn bitand_assign(&mut self, rhs: ShapeFlags)

Performs the &= operation.

impl BitOr for ShapeFlags

type Output = ShapeFlags

The resulting type after applying the | operator.

fn bitor(self, rhs: ShapeFlags) -> ShapeFlags

Performs the | operation.

impl BitOrAssign for ShapeFlags

The resulting type after applying the ^ operator.

fn bitxor(self, rhs: ShapeFlags) -> ShapeFlags

Performs the ^ operation.

impl BitXorAssign for ShapeFlags

fn bitxor_assign(&mut self, rhs: ShapeFlags)

Performs the ^= operation.

impl Clone for ShapeFlags

fn clone(&self) -> ShapeFlags

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ShapeFlags

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

Formats the value using the given formatter.

impl Default for ShapeFlags

fn default() -> ShapeFlags

Returns the “default value” for a type.

impl Hash for ShapeFlags

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Not for ShapeFlags

type Output = ShapeFlags

The resulting type after applying the ! operator.

fn not(self) -> ShapeFlags

Performs the unary ! operation.

impl PartialEq for ShapeFlags

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