Struct TypeFlags

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

Flags describing properties of a type

Implementations

impl TypeFlags

Is the type self-contained in a register

pub const IS_STORAGE: Self

Can it be stored in a sum or product type

pub const IS_ALLOWED_RETURN: Self

pub const ALLOWED_FOR_VARIABLE: Self

pub const fn new() -> Self

pub const fn contains(self, flag: Self) -> bool

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

pub fn compute_for_type_kind(kind: &TypeKind) -> Self

Compute type flags based on the TypeKind

Trait Implementations

impl Clone for TypeFlags

fn clone(&self) -> TypeFlags

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TypeFlags

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

Formats the value using the given formatter.

impl Default for TypeFlags

fn default() -> Self

Returns the “default value” for a type.

impl Hash for TypeFlags

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

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 PartialEq for TypeFlags

fn eq(&self, other: &TypeFlags) -> 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 Copy for TypeFlags
