Struct BindingModifier 

pub struct BindingModifier { /* private fields */ }

Set of wire modifiers carried by one binding declaration. Stored as a bitset under the hood; consumers use Self::has to test for individual modifiers and Self::insert / Self::from_iter to build instances.

Validity: the combination const + volatile is rejected at parse time as contradictory (Self::from_iter is the validating builder). All other combinations are representable.

Lives on every Statement::Binding — the modifier set determines the binding’s lifecycle. Other statement kinds (ExternPort, InputDecl, etc.) don’t carry modifiers because their semantics are fixed by their statement form.

Implementations

impl BindingModifier

pub const NONE: BindingModifier

All-modifiers-off; the default state of an unannotated binding (per-cycle).

pub const CONST: BindingModifier

Single-modifier convenience constants. Tests reach for these to express their intent compactly.

pub const SHARED: BindingModifier

The shared modifier alone.

pub const VOLATILE: BindingModifier

The volatile modifier alone.

pub const fn has(&self, m: WireModifier) -> bool

true iff m is set.

pub const fn has_any(&self) -> bool

true iff at least one modifier is set.

pub fn insert(&mut self, m: WireModifier)

Add m to the set.

pub fn try_from_iter<I>(items: I) -> Result<BindingModifier, &'static str>

where I: IntoIterator<Item = WireModifier>,

Build a modifier set from an iterator of variants. The parser uses this after collecting tokens. Rejects the contradictory const + volatile combo with a clear error.

pub fn iter(&self) -> impl Iterator<Item = WireModifier>

Iterate the modifiers in the set, in fixed declaration order (Const, Shared, Volatile). Used for re-emission and stable hash output.

pub const fn is_const(&self) -> bool

Direct field-style accessors retained for sites that pattern-match on individual flags. Mechanically derive from has(...) so adding a new modifier is one variant

• one bit assignment + (optionally) one accessor.

pub const fn is_shared(&self) -> bool

true iff shared is set.

pub const fn is_volatile(&self) -> bool

true iff volatile is set.
