Methods

impl Restrictions

const RESTRICTION_STMT_EXPR: Restrictions = Restrictions{bits: 1 << 0,}

const RESTRICTION_NO_STRUCT_LITERAL: Restrictions = Restrictions{bits: 1 << 1,}

const NO_NONINLINE_MOD: Restrictions = Restrictions{bits: 1 << 2,}

fn empty() -> Restrictions

Unstable (rustc_private)

Returns an empty set of flags.

fn all() -> Restrictions

Unstable (rustc_private)

Returns the set containing all flags.

fn bits(&self) -> u8

Unstable (rustc_private)

Returns the raw value of the flags currently stored.

fn from_bits(bits: u8) -> Option<Restrictions>

Unstable (rustc_private)

Convert from underlying bit representation, unless that representation contains bits that do not correspond to a flag.

fn from_bits_truncate(bits: u8) -> Restrictions

Unstable (rustc_private)

Convert from underlying bit representation, dropping any bits that do not correspond to flags.

fn is_empty(&self) -> bool

Unstable (rustc_private)

Returns true if no flags are currently stored.

fn is_all(&self) -> bool

Unstable (rustc_private)

Returns true if all flags are currently set.

fn intersects(&self, other: Restrictions) -> bool

Unstable (rustc_private)

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

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

Unstable (rustc_private)

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

fn insert(&mut self, other: Restrictions)

Unstable (rustc_private)

Inserts the specified flags in-place.

fn remove(&mut self, other: Restrictions)

Unstable (rustc_private)

Removes the specified flags in-place.

fn toggle(&mut self, other: Restrictions)

Unstable (rustc_private)

Toggles the specified flags in-place.

Derived Implementations

impl Hash for Restrictions

fn hash<__H: Hasher>(&self, __arg_0: &mut __H)
