Types

Binary

</> 
pub type Binary {
  Binary(version: Int, length: Int, module: module.Module)
}

Constructors 

  • Binary(version: Int, length: Int, module: module.Module)

Code

</> 
pub type Code {
  Code(size: Int, function_code: FunctionCode)
}

Constructors 

  • Code(size: Int, function_code: FunctionCode)

FunctionCode

</> 
pub type FunctionCode {
  FunctionCode(
    locals: convention.Vector(LocalsDeclaration),
    body: instruction.Expression,
  )
}

Constructors 

  • FunctionCode(
  locals: convention.Vector(LocalsDeclaration),
  body: instruction.Expression,
)

</> 
pub type LocalsDeclaration {
  LocalsDeclaration(count: Int, type_: types.ValueType)
}

Constructors

Section

</>

Each section consists of - a one-byte section id, - the u32 size of the contents, in bytes, - the actual contents, whose structure is dependent on the section id. https://webassembly.github.io/spec/core/binary/module.html#sections

pub type Section {
  Section(id: Int, length: Int, content: Option(SectionContent))
}

Constructors 

  • Section(id: Int, length: Int, content: Option(SectionContent))

SectionContent

</> 
pub type SectionContent {
  CustomSection(name: String, data: Option(BitArray))
  TypeSection(
    function_types: convention.Vector(types.FunctionType),
  )
  ImportSection
  FunctionSection(type_indices: convention.Vector(Int))
  TableSection
  MemorySection(memories: convention.Vector(module.Memory))
  GlobalSection(globals: convention.Vector(module.Global))
  ExportSection(exports: convention.Vector(module.Export))
  StartSection(start_function: module.StartFunction)
  ElementSection
  CodeSection(entries: List(Code))
  DataSection
  DataCountSection
}

Constructors 

  • CustomSection(name: String, data: Option(BitArray))

    Custom sections have the id 0. They are intended to be used for debugging information or third-party extensions, and are ignored by the WebAssembly semantics. Their contents consist of a name further identifying the custom section, followed by an uninterpreted sequence of bytes for custom use.

    https://webassembly.github.io/spec/core/binary/module.html#custom-section

  • TypeSection(
  function_types: convention.Vector(types.FunctionType),
)

    The type section has the id 1. It decodes into a vector of function types that represent the component of a module.

    https://webassembly.github.io/spec/core/binary/module.html#type-section

  • ImportSection
  • FunctionSection(type_indices: convention.Vector(Int))

    The function section has the id 3. It decodes into a vector of type indices that represent the fields of the functions in the component of a module. The and

    fields of the respective functions are encoded separately in the code section.

    https://webassembly.github.io/spec/core/binary/module.html#function-section

  • TableSection

    The table section has the id 4. It decodes into a vector of tables that represent the

    component of a module.

    https://webassembly.github.io/spec/core/binary/modules.html#table-section

  • MemorySection(memories: convention.Vector(module.Memory))

    The memory section has the id 5. It decodes into a vector of memories that represent the component of a module.

    https://webassembly.github.io/spec/core/binary/modules.html#memory-section

  • GlobalSection(globals: convention.Vector(module.Global))

    The global section has the id 6. It decodes into a vector of globals that represent the component of a module.

    https://webassembly.github.io/spec/core/binary/modules.html#global-section

  • ExportSection(exports: convention.Vector(module.Export))

    The export section has the id 7. It decodes into a vector of exports that represent the exports component of a module.

    https://webassembly.github.io/spec/core/binary/module.html#export-section

  • StartSection(start_function: module.StartFunction)

    The start section has the id 8. It decodes into an optional start function that represents the component of a module.

    https://webassembly.github.io/spec/core/binary/modules.html#start-section
