Enum SandboxError 

pub enum SandboxError {
    RuleTimeout {
        budget: Duration,
    },
    RunTimeout {
        budget: Duration,
        elapsed: Duration,
    },
    MemoryExceeded {
        limit_bytes: usize,
    },
    Script {
        message: String,
        stack: Option<String>,
    },
    NonErrorThrown,
    Engine(String),
}

A failure inside the sandbox.

Every variant here aborts the run. Skipping the offending rule and continuing is the friendlier-looking behavior and is wrong: a timeout is timing-dependent, so a rule that trips on a loaded machine and not on an idle one would make output vary between runs on identical input — the property the rest of the design works to prevent. A checker that could not finish must not be mistaken for one that found nothing.

Variants

RuleTimeout

One handler invocation exceeded its budget.

Fields

budget: Duration

The budget that was exceeded.

RunTimeout

The run as a whole exceeded its wall-clock budget.

Fields

budget: Duration

The global budget.

elapsed: Duration

How long the run had actually been going.

MemoryExceeded

The runtime hit its memory ceiling.

Fields

limit_bytes: usize

The ceiling that was hit.

Script

The rule threw, or failed to parse.

Fields

message: String

The thrown value’s message.

stack: Option<String>

The stack trace, if the thrown value carried one.

NonErrorThrown

The rule threw something that is not an Error.

Engine(String)

The engine failed for a reason lanekeep does not model.

Implementations

impl SandboxError

pub const fn is_limit_breach(&self) -> bool

Whether this failure came from a breached limit rather than from rule logic.

Both cancel the run. The distinction is for the diagnostic: a limit breach is a budget problem, a thrown error is a bug in the rule.

Trait Implementations

impl Clone for SandboxError

fn clone(&self) -> SandboxError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SandboxError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for SandboxError

fn fmt(&self, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for SandboxError

impl Error for SandboxError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl PartialEq for SandboxError

fn eq(&self, other: &SandboxError) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
