Yury Delendik	15c68f2cc1	Disconnects `Store` state fields from `Compiler` (#1761 ) * Moves CodeMemory, VMInterrupts and SignatureRegistry from Compiler * CompiledModule holds CodeMemory and GdbJitImageRegistration * Store keeps track of its JIT code * Makes "jit_int.rs" stuff Send+Sync * Adds the threads example.	4 years ago
Dan Gohman	9364eb1d98	Refactor (#1524 ) * Compute instance exports on demand. Instead having instances eagerly compute a Vec of Externs, and bumping the refcount for each Extern, compute Externs on demand. This also enables `Instance::get_export` to avoid doing a linear search. This also means that the closure returned by `get0` and friends now holds an `InstanceHandle` to dynamically hold the instance live rather than being scoped to a lifetime. * Compute module imports and exports on demand too. And compute Extern::ty on demand too. * Add a utility function for computing an ExternType. * Add a utility function for looking up a function's signature. * Add a utility function for computing the ValType of a Global. * Rename wasmtime_environ::Export to EntityIndex. This helps differentiate it from other Export types in the tree, and describes what it is. * Fix a typo in a comment. * Simplify module imports and exports. * Make `Instance::exports` return the export names. This significantly simplifies the public API, as it's relatively common to need the names, and this avoids the need to do a zip with `Module::exports`. This also changes `ImportType` and `ExportType` to have public members instead of private members and accessors, as I find that simplifies the usage particularly in cases where there are temporary instances. * Remove `Instance::module`. This doesn't quite remove `Instance`'s `module` member, it gets a step closer. * Use a InstanceHandle utility function. * Don't consume self in the `Func::get` methods. Instead, just create a closure containing the instance handle and the export for them to call. Use `ExactSizeIterator` to avoid needing separate `num_` methods. Rename `Extern::func()` etc. to `into_func()` etc. * Revise examples to avoid using `nth`. * Add convenience methods to instance for getting specific extern types. * Use the convenience functions in more tests and examples. * Avoid cloning strings for `ImportType` and `ExportType`. * Remove more obviated clone() calls. * Simplify `Func`'s closure state. * Make wasmtime::Export's fields private. This makes them more consistent with ExportType. * Fix compilation error. * Make a lifetime parameter explicit, and use better lifetime names. Instead of 'me, use 'instance and 'module to make it clear what the lifetime is. * More lifetime cleanups.	5 years ago
Alex Crichton	0d4bde4ab3	Add a `wasmtime::Linker` type (#1384 ) * Add a `wasmtime::Linker` type This commit adds a new type to the `wasmtime` crate, a `Linker`. This linker is intended to vastly simplify calling `Instance::new` by easily performing name resolution and incrementally defining state over time. The goal here is to start down a path of making linking wasm modules in `wasmtime` a first-class and ergonomic operation. This is highly likely to evolve over time and get tweaked through releases as we iterate towards a design well-suited for `wasmtime`, but this is intended to at least be the initial foundation for such functionality. This commit additionally also adds a C API for the linker and switches the existing linking examples to using this linker in both Rust and C. One piece of future work I'd like to tackle next is to integrate WASI into the `wasmtime` crate in a more first-class manner. This [`Linker`] type provides a great location to hook into the instantiation process to easily instantiate modules with WASI imports. That's a relatively large refactoring for now though and I figured it'd be best left for a different time. Closes #727	5 years ago
Alex Crichton	e245e6dd9c	Add examples of linking and WASI (#1369 ) * Add examples of linking and WASI This commit adds two example programs, one for linking two modules together and one for instantiating WASI. The linkage example additionally uses WASI to get some meaningful output at this time. cc #1272 * Add examples to the book as well * More links! * Ignore examples from rustdoc testsing * More example updates * More ignored	5 years ago
