Expand description

A trap code describing the reason for a trap.

All trap instructions have an explicit trap code.

Variants

StackOverflow

The current stack space was exhausted.

HeapOutOfBounds

A heap_addr instruction detected an out-of-bounds error.

Note that not all out-of-bounds heap accesses are reported this way; some are detected by a segmentation fault on the heap unmapped or offset-guard pages.

HeapMisaligned

A wasm atomic operation was presented with a not-naturally-aligned linear-memory address.

TableOutOfBounds

A table_addr instruction detected an out-of-bounds error.

IndirectCallToNull

Indirect call to a null table entry.

BadSignature

Signature mismatch on indirect call.

IntegerOverflow

An integer arithmetic operation caused an overflow.

IntegerDivisionByZero

An integer division by zero.

BadConversionToInteger

Failed float-to-int conversion.

UnreachableCodeReached

Code that was supposed to have been unreachable was reached.

Interrupt

Execution has potentially run too long and may be interrupted. This trap is resumable.

User(u16)

A user-defined trap code.
