Compiler CompilerOptions ConstantCompiler Engine The Wasm engine holds the state of the interpreter and the WebAssembly store Expr Func FuncType GlobalType GlobalValueError GlobalVariable The decoded representation of a global variable HostFunction HostGlobal HostModule HostModuleRef HostName A bounded, inline, owned host name (module / function / global / symbol). HostNameError Error returned when a host name exceeds [HOST_NAME_CAP] bytes or is not
valid UTF-8. HostRef A general purpose reference to a symbol in a host module HostSymbol HostValList An owned, bounded list of ValTypei (i32), I (i64), f (f32), d (f64). HostValListError Error returned when a host value signature contains an invalid character or
exceeds HOST_SIGNATURE_CAP HostValListIter Interpreter JumpOffset A relative offset to jump to from the current program counter JumpTarget A 32-bit address into the paged IR code. LabelTarget A 32-bit value encoding a label’s arity, jump address, and stack truncation information
[arity:2][depth:8][offset:22] Limit LocalVariable MemArg MemType Memory MemoryStatistics ModuleRef An index offset from the current module.
Module imports can only refer to modules loaded before it.
References store a relative offset from the ‘current’ module. 0 indicates the current module. Name A pointer and length into a UTF-8 string on the original Wasm RawValue A compile-time/configured value Reader A struct for managing and reading Wasm bytecode
Its purpose is to abstract parsing basic Wasm values from the bytecode
and managing the chunks from a stream as they are read. ResultType Stack Store Holds ownership of all the loaded modules. As new modules are loaded,
imports/exports are referenced through the store. TableType TextBuilder High-level builder for compiled IR that handles control flow and instruction encoding. TextPage A page of compiled IR code containing 256 16-bit words (512 bytes). WasmRef A reference to a Wasm symbol in the store BlockKind ConstantExprError ElemType HostFunctionBreak Import InterpreterBreak InterpreterResult InvokeError LabelArity MemPageSize MemoryError Ref A reference to a symbol in the Wasm store relative to an implicit ‘self’ module StartInvocation TrapReason ValType Value types classify the individual values that WebAssembly code can compute with and the values
that a variable accepts.
https://www.w3.org/TR/wasm-core-1/#syntax-valtype Value A runtime type-tracked value HOST_FUNCTION_NAME_CAP HOST_GLOBAL_NAME_CAP HOST_MODULE_NAME_CAP HOST_SIGNATURE_CAP Maximum number of values in a host function parameter / result signature. BaseVisitor An abstraction over Wasm IR and internal IR.
This trait can be used to index, compile and execute either form of IR
with the same common implementation. The decoding and traversal code will
call into this visitor and is IR specific. This trait is purely for operating
on decoded WebAssembly instructions. GlobalValue InterpreterRunner This is a meta-trait that provides an auto implementation of run() for all IrVisitors
of a certain shape. IrVisitor An abstraction over IR Bytecode.
Used to implement the interpreter. WasmMemoryAllocator An allocator for allocating Wasm pages WasmStream WasmVisitor An abstraction over Wasm Bytecode.
Used to implement validation and compilation of Wasm bytecode. HostFunctionFn HostFunctionResult
