Struct WatchTerms 

pub struct WatchTerms {
    pub limit: Duration,
    pub cadence: Cadence,
    pub notices: Box<dyn Write + Send>,
}

What: When a watched wait prints and where it stops the child. Why: The production entry reads these from the environment and writes to standard error; tests choose short ones and read the notices from a buffer.

In TS you’d write (pseudocode):

type WatchTerms = { limitMs: number; cadence: Cadence; notices: Writable };

Fields

limit: Duration

How long one wait may last before the child is stopped.

cadence: Cadence

When the notices of a wait are due.

notices: Box<dyn Write + Send>

Where the notices go.

Implementations

impl WatchTerms

pub fn from_environment() -> Self

The terms this process runs under: the variables of its environment, notices on standard error.
