Struct ScriptFailure 

pub struct ScriptFailure {
    pub whence: String,
    pub stop: ScriptStop,
}

Available on crate feature javascript only.

One script that stopped, named and explained.

An uncaught exception is never swallowed. The error is reported on the diagnostic channel and the next script still runs; the transcript is unaffected, because a throwing script prints nothing to it. [oracle-bug]: the oracle drops the error entirely, so a fixture that crashes on its first line reads as an empty transcript and scores as a pass.

Fields

whence: String

Which script — a field’s fully-qualified name, a /Names /JavaScript key, or the empty string for /OpenAction.

stop: ScriptStop

Why it stopped.

Implementations

impl ScriptFailure

pub fn line(&self) -> String

The failure as one diagnostic line: where, and what the engine said.

The position rides in the message — a throw reads TypeError: not a callable function (unknown at :1:25) — so there is no separate line/column pair.

Only the first line of it:

boa appends a stack — \n at <main> (…) — after the message. A diagnostic is a line, and a caller writing one per failure must not have a multi-line one break its format. ScriptStop::Threw keeps the whole string for a caller that wants it.
