Inflated version of WasmFeatures that allows for exhaustive matching on fields.

Fields

mutable_global: bool

The WebAssembly mutable-global proposal. Defaults to true.

saturating_float_to_int: bool

The WebAssembly saturating-float-to-int proposal. Defaults to true.

sign_extension: bool

The WebAssembly sign-extension-ops proposal. Defaults to true.

reference_types: bool

The WebAssembly reference types proposal. Defaults to true.

multi_value: bool

The WebAssembly multi-value proposal. Defaults to true.

bulk_memory: bool

The WebAssembly bulk memory operations proposal. Defaults to true.

simd: bool

The WebAssembly SIMD proposal. Defaults to true.

relaxed_simd: bool

The WebAssembly Relaxed SIMD proposal. Defaults to true.

threads: bool

The WebAssembly threads proposal. Defaults to true.

shared_everything_threads: bool

The WebAssembly shared-everything-threads proposal; includes new component model built-ins. Defaults to false.

tail_call: bool

The WebAssembly tail-call proposal. Defaults to true.

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. Defaults to true.

multi_memory: bool

The WebAssembly multi memory proposal. Defaults to true.

exceptions: bool

The WebAssembly exception handling proposal. Defaults to false.

memory64: bool

The WebAssembly memory64 proposal. Defaults to false.

extended_const: bool

The WebAssembly extended_const proposal. Defaults to true.

component_model: bool

The WebAssembly component model proposal. Defaults to true.

function_references: bool

The WebAssembly typed function references proposal. Defaults to false.

memory_control: bool

The WebAssembly memory control proposal. Defaults to false.

gc: bool

The WebAssembly gc proposal. Defaults to false.

custom_page_sizes: bool

The WebAssembly custom-page-sizes proposal. Defaults to false.

component_model_values: bool

Support for the value type in the component model proposal. Defaults to false.

component_model_nested_names: bool

Support for the nested namespaces and projects in component model names. Defaults to false.

component_model_more_flags: bool

Support for more than 32 flags per-type in the component model. Defaults to false.
