Crate wasmer_types[−][src]
Expand description
This are the common types and utility tools for using WebAssembly in a Rust environment.
This crate provides common structures such as Type
or Value
, type indexes
and native function wrappers with Func
.
Modules
entity | The entity module, with common helpers for Rust structures |
lib | The |
Macros
entity_impl | Macro which provides the common implementation of a 32-bit entity reference. |
Structs
ArchivableIndexMap | Rkyv Archivable IndexMap |
Atomically | Atomically. |
Bytes | Units of WebAssembly memory in terms of 8-bit bytes. |
CustomSectionIndex | Index type of a custom section inside a WebAssembly module. |
DataIndex | Index type of a passive data segment inside the WebAssembly module. |
DataInitializer | A data initializer for linear memory. |
DataInitializerLocation | A memory index and offset within that memory where a data initialization should be performed. |
ElemIndex | Index type of a passive element segment inside the WebAssembly module. |
ExportType | A descriptor for an exported WebAssembly value. |
ExternRef | An opaque reference to some data. This reference can be passed through Wasm. |
Features | Controls which experimental features will be enabled. Features usually have a corresponding WebAssembly proposal. |
FunctionIndex | Index type of a function (imported or local) inside the WebAssembly module. |
FunctionType | The signature of a function that is either implemented in a Wasm module or exposed to Wasm by the host. |
GlobalIndex | Index type of a global variable (imported or local) inside the WebAssembly module. |
GlobalType | WebAssembly global. |
ImportType | A descriptor for an imported value into a wasm module. |
LocalFunctionIndex | Index type of a function defined locally inside the WebAssembly module. |
LocalGlobalIndex | Index type of a global defined locally inside the WebAssembly module. |
LocalMemoryIndex | Index type of a memory defined locally inside the WebAssembly module. |
LocalTableIndex | Index type of a table defined locally inside the WebAssembly module. |
MemoryIndex | Index type of a linear memory (imported or local) inside the WebAssembly module. |
MemoryType | A descriptor for a WebAssembly memory type. |
MemoryView | A view into a memory. |
OwnedDataInitializer | As |
PageCountOutOfRange | The only error that can happen when converting |
Pages | Units of WebAssembly pages (as specified to be 65,536 bytes). |
SignatureIndex | Index type of a signature (imported or local) inside the WebAssembly module. |
TableIndex | Index type of a table (imported or local) inside the WebAssembly module. |
TableInitializer | A WebAssembly table initializer. |
TableType | A descriptor for a table in a WebAssembly module. |
V128 | The WebAssembly V128 type |
VMExternRef | This type does not do reference counting automatically, reference counting can be done with
|
Enums
ExportIndex | An entity to export. |
ExternType | A list of all possible types which can be externally referenced from a WebAssembly module. |
GlobalInit | Globals are initialized via the |
ImportIndex | An entity to import. |
Mutability | Indicator of whether a global is mutable or not |
Type | A list of all possible value types in WebAssembly. |
Value | Possible runtime values that a WebAssembly module can either consume or produce. |
Constants
VERSION | Version number of this crate. |
WASM_MAX_PAGES | The number of pages we can have before we run out of byte index space. |
WASM_MIN_PAGES | The minimum number of pages allowed. |
WASM_PAGE_SIZE | WebAssembly page sizes are fixed to be 64KiB. Note: large page support may be added in an opt-in manner in the future. |
Traits
NativeWasmType |
|
ValueType | Trait for a Value type. A Value type is a type that is always valid and may be safely copied. |
WasmValueType | Trait for reading and writing Wasm values into binary for use on the layer
between the API and the VM internals, specifically with |
