Struct SignalFlags 

pub struct SignalFlags {
    pub sigusr1: Arc<AtomicBool>,
    pub sigwinch: Arc<AtomicBool>,
}

Shared flags set by signal handlers and polled by the main loop.

Fields

sigusr1: Arc<AtomicBool>

Set when SIGUSR1 has been received (FR-030 — re-stat input file).

sigwinch: Arc<AtomicBool>

Set when SIGWINCH has been received (FR-019 — re-query terminal width).

Implementations

impl SignalFlags

pub fn new() -> Self

Construct a fresh, cleared set of flags.

pub fn take_sigusr1(&self) -> bool

Atomically consume the SIGUSR1 flag. Returns true if it was set.

pub fn take_sigwinch(&self) -> bool

Atomically consume the SIGWINCH flag. Returns true if it was set.
