SignalMask

Struct SignalMask 

Source
pub struct SignalMask(/* private fields */);
Expand description

Ensemble de signaux représenté comme bitmask u64.

Le bit N du mask correspond au signal N + 1 (convention Linux sigset_t : signal 1 = bit 0, signal 64 = bit 63). Les signaux au-delà de 64 (RT signals étendus, rares) ne sont pas représentables par ce stub — ils seront supportés via une représentation plus large si nécessaire dans une PR ultérieure.

Implementations§

Source§

impl SignalMask

Source

pub const fn empty() -> Self

Masque vide (aucun signal).

Source

pub const fn from_bits(bits: u64) -> Self

Construit depuis sa représentation brute.

Source

pub const fn bits(self) -> u64

Représentation brute (bits 0-63 = signaux 1-64).

Source

pub fn from_signals(signals: &[Signal]) -> Self

Construit un mask à partir d’une liste de signaux. Les signaux au-delà de 64 (rares) sont silencieusement ignorés.

Source

pub fn contains(self, sig: Signal) -> bool

Indique si sig est dans le mask.

Défense en profondeur. Le type Signal borne déjà ses valeurs à [1, 64] (cf. Signal::try_from_raw), donc bit_index < 64 par construction et la branche None de checked_shl est structurellement inatteignable. Elle est conservée comme garde no-op (retourne false) au cas où un futur constructeur de Signal oublierait d’appliquer la borne — Principe 5 : sur-sécuriser, ne jamais corrompre.

Source

pub fn with(self, sig: Signal) -> Self

Retourne un nouveau mask avec sig ajouté.

Même garde no-op défensive que Self::contains : si jamais bit_index >= 64, retourne le mask inchangé (sans paniquer ni corrompre l’état).

Source

pub fn without(self, sig: Signal) -> Self

Retourne un nouveau mask avec sig retiré.

Même garde no-op défensive que Self::contains.
