Module parity_wasm::elements
source · [−]Expand description
Elements of the WebAssembly binary format.
Modules
Structs
Section with function bodies of the module.
List for reading sequence of elements typed T, given
they are preceded by length (serialized as VarUint32).
Helper struct to write series of T preceded by the length of the sequence
serialized as VarUint32.
Helper struct to write payload which is preceded by it’s own length in bytes.
Custom section.
Data entries definitions.
Data segment definition.
Element entries section.
Entry in the element section.
Export entry.
List of exports definition.
Function signature (type reference)
Function body definition.
The names of the functions in this module.
Section with function signatures definition.
Function signature type.
Global entry in the module.
Globals definition section.
Global definition struct
Import entry.
Section of the imports definition.
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.
Initialization expression.
List of instructions (usually inside a block section).
Local definition inside the function body.
The names of the local variables in this module’s functions.
Section with table definition (currently only one entry is allowed).
Memory entry.
WebAssembly module
The name of this module.
Debug name information.
Relocation information.
Memory and table limits.
Section with table definition (currently only one is allowed).
Table entry
Section with type declarations.
8-bit unsigned integer, NOT encoded in LEB128; it’s just a single byte.
32-bit unsigned integer, encoded in little endian.
64-bit unsigned integer, encoded in little endian.
Unparsed part of the module/section.
7-bit signed integer, encoded in LEB128 (always 1 byte length)
32-bit signed integer, encoded in LEB128 (can be 1-5 bytes length).
64-bit signed integer, encoded in LEB128 (can be 1-9 bytes length).
VarUint1, 1-bit value (0/1).
7-bit unsigned integer, encoded in LEB128 (always 1 byte length).
Unsigned variable-length integer, limited to 32 bits, represented by at most 5 bytes that may contain padding 0x80 bytes.
Unsigned variable-length integer, limited to 64 bits, represented by at most 9 bytes that may contain padding 0x80 bytes.
Enums
Block type which is basically ValueType + NoResult (to define blocks that have no return type)
Deserialization/serialization error
External to local binding.
Type of the import entry to count
Instruction.
Internal reference of the exported entry.
Relocation entry.
Section in the WebAssembly module.
Table element type.
Type definition in types section. Currently can be only of the function type.
Value type.
Traits
Deserialization from serial i/o.
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 deserializable type from buffer.
Deserialize module from the file.
Returns size of the module in the provided stream.
Create buffer with serialized value.
Serialize module to the file
Type Definitions
A map from indices to names.
