[−][src]Module parity_wasm::elements

Elements of the WebAssembly binary format.

Modules

Structs

CodeSection	Section with function bodies of the module.
CountedList	List for reading sequence of elements typed `T`, given they are preceded by length (serialized as VarUint32)
CountedListWriter	Helper struct to write series of `T` preceded by the length of the sequence serialized as VarUint32
CountedWriter	Helper struct to write payload which is preceded by it's own length in bytes.
CustomSection	Custom section
DataSection	Data entries definitions.
DataSegment	Data segment definition.
ElementSection	Element entries section.
ElementSegment	Entry in the element section.
ExportEntry	Export entry.
ExportSection	List of exports definition.
Func	Function signature (type reference)
FuncBody	Function body definition.
FunctionNameSection	The names of the functions in this module.
FunctionSection	Section with function signatures definition.
FunctionType	Function signature type.
GlobalEntry	Global entry in the module.
GlobalSection	Globals definition section.
GlobalType	Global definition struct
ImportEntry	Import entry.
ImportSection	Section of the imports definition.
IndexMap	A map from non-contiguous `u32` keys to values of type `T`, which is serialized and deserialized ascending order of the keys. Normally used for relative dense maps with occasional "holes", and stored as an array.
InitExpr	Initialization expression.
Instructions	List of instructions (usually inside a block section).
Local	Local definition inside the function body.
LocalNameSection	The names of the local variables in this module's functions.
MemorySection	Section with table definition (currently only one entry is allowed).
MemoryType	Memory entry.
Module	WebAssembly module
ModuleNameSection	The name of this module.
RelocSection	Relocation information.
ResizableLimits	Memory limits
TableSection	Section with table definition (currently only one is allowed).
TableType	Table entry
TypeSection	Section with type declarations
Uint8	8-bit unsigned integer, NOT encoded in LEB128; it's just a single byte.
Uint32	32-bit unsigned integer, encoded in little endian
Uint64	64-bit unsigned integer, encoded in little endian
Unparsed	Unparsed part of the module/section
VarInt7	7-bit signed integer, encoded in LEB128 (always 1 byte length)
VarInt32	32-bit signed integer, encoded in LEB128 (can be 1-5 bytes length)
VarInt64	64-bit signed integer, encoded in LEB128 (can be 1-9 bytes length)
VarUint1	VarUint1, 1-bit value (0/1)
VarUint7	7-bit unsigned integer, encoded in LEB128 (always 1 byte length)
VarUint32	Unsigned variable-length integer, limited to 32 bits, represented by at most 5 bytes that may contain padding 0x80 bytes.
VarUint64	Unsigned variable-length integer, limited to 64 bits, represented by at most 9 bytes that may contain padding 0x80 bytes.

Enums

BlockType	Block type which is basically `ValueType` + NoResult (to define blocks that have no return type)
Error	Deserialization/serialization error
External	External to local binding.
ImportCountType	Type of the import entry to count
Instruction	Instruction
Internal	Internal reference of the exported entry.
NameSection	Debug name information.
RelocationEntry	Relocation entry.
Section	Section in the WebAssembly module.
TableElementType	Table element type.
Type	Type definition in types section. Currently can be only of the function type.
ValueType	Value type.

Traits

Deserialize	Deserialization from serial i/o
Serialize	Serialization to serial i/o. Takes self by value to consume less memory (parity-wasm IR is being partially freed by filling the result buffer).

Functions

deserialize_buffer	Deserialize deserializable type from buffer.
deserialize_file	Deserialize module from the file.
peek_size	Returns size of the module in the provided stream
serialize	Create buffer with serialized value.
serialize_to_file	Serialize module to the file

Type Definitions

NameMap

A map from indices to names.
