Struct EvaluatorOptions 

pub struct EvaluatorOptions {
    pub timeout_ms: Option<u64>,
    pub max_stack_depth: Option<usize>,
    pub max_sequence_length: Option<usize>,
}

Resource-limit guardrails, mirroring jsonata-js 2.2.1’s timeout/stack/sequence evaluator options. All fields default to None = unlimited (current behavior).

Fields

timeout_ms: Option<u64>

Maximum wall-clock evaluation time in milliseconds. Exceeding it raises D1012.

max_stack_depth: Option<usize>

Maximum AST-recursion stack depth. Exceeding it raises D1011 if this is the tighter of this value and the hardcoded native-stack safety ceiling (302); otherwise the hardcoded ceiling still raises U1001 (see GitHub issue #34).

max_sequence_length: Option<usize>

Maximum length of a query-result sequence (map/filter/wildcard/descendants/ keys/lookup/append/spread/each/range/path-mapping). Exceeding it raises D2015. Does NOT currently apply to literal array construction (MakeArray/ ArrayConstruct) — NOTE this is a deliberate, temporary divergence from upstream, not a match: jsonata-js DOES cap flat/non-nested array literals (via fn.append’s createSequence hook in evaluateUnary’s [ case). Deferred until the separate MakeArray(u16) truncation bug is fixed (see the design spec’s “Sequence length → D2015” section).
