The closed set of lowering failures.

Variants

JavaScriptSourceNeedsCompatibility

A JavaScript source was lowered without javascript_compatibility.

Fields

script_kind: ScriptKind

JsonSourceNotExecutable

JSON sources have no executable statement semantics.

MissingSyntax

A parser recovery node reached lowering.

Fields

expected: NodeKind

InvalidNumericLiteral

A numeric literal lexeme did not denote a finite deterministic value.

InvalidBigIntLiteral

A bigint literal lexeme did not denote a canonical integer value.

InvalidRegexLiteral

A regular-expression literal lexeme was malformed.

IllFormedMetadataString

A module linkage name contained an unpaired UTF-16 surrogate.

Unsupported(UnsupportedConstruct)

A runtime construct the current instruction set cannot express.

Capacity(CapacityLimit)

A structural production capacity ran out.

Verify(VerifyError)

The assembled module failed bytecode verification. Lowering maintains every verifier invariant by construction, so this is defensive.
