Properties
bulkMemory → bool
The WebAssembly bulk memory operations proposal (enabled by default)
final
componentModel → bool
The WebAssembly component model proposal.
final
exceptions → bool
The WebAssembly exception handling proposal
final
extendedConst → bool
The WebAssembly extended_const proposal
final
floats → bool
Whether or not floating-point instructions are enabled.
This is enabled by default can be used to disallow floating-point operators and types.
This does not correspond to a WebAssembly proposal but is instead intended for embeddings which have
stricter-than-usual requirements about execution. Floats in WebAssembly can have different NaN patterns
across hosts which can lead to host-dependent execution which some runtimes may not desire.
final
functionReferences → bool
The WebAssembly typed function references proposal
final
gc → bool
The WebAssembly gc proposal
final
hashCode → int
The hash code for this object.
no setter override
memory64 → bool
The WebAssembly memory64 proposal
final
memoryControl → bool
The WebAssembly memory control proposal
final
multiMemory → bool
The WebAssembly multi memory proposal
final
multiValue → bool
The WebAssembly multi-value proposal (enabled by default)
final
mutableGlobal → bool
The WebAssembly mutable-global proposal (enabled by default)
final
referenceTypes → bool
The WebAssembly reference types proposal (enabled by default)
final
relaxedSimd → bool
The WebAssembly Relaxed SIMD proposal
final
runtimeType → Type
A representation of the runtime type of the object.
no setter inherited
saturatingFloatToInt → bool
The WebAssembly nontrapping-float-to-int-conversions proposal (enabled by default)
final
signExtension → bool
The WebAssembly sign-extension-ops proposal (enabled by default)
final
simd → bool
The WebAssembly SIMD proposal (enabled by default)
final
tailCall → bool
The WebAssembly tail-call proposal
final
