Struct wasmer_types::compilation::function::Compilation

pub struct Compilation {
    pub functions: Functions,
    pub custom_sections: CustomSections,
    pub function_call_trampolines: PrimaryMap<SignatureIndex, FunctionBody>,
    pub dynamic_function_trampolines: PrimaryMap<FunctionIndex, FunctionBody>,
    pub debug: Option<Dwarf>,
}

The result of compiling a WebAssembly module’s functions.

Fields

functions: Functions

Compiled code for the function bodies.

custom_sections: CustomSections

Custom sections for the module. It will hold the data, for example, for constants used in a function, global variables, rodata_64, hot/cold function partitioning, …

function_call_trampolines: PrimaryMap<SignatureIndex, FunctionBody>

Trampolines to call a function defined locally in the wasm via a provided Vec of values.

This allows us to call easily Wasm functions, such as:

let func = instance.exports.get_function("my_func");
func.call(&[Value::I32(1)]);

dynamic_function_trampolines: PrimaryMap<FunctionIndex, FunctionBody>

Trampolines to call a dynamic function defined in a host, from a Wasm module.

This allows us to create dynamic Wasm functions, such as:

fn my_func(values: &[Val]) -> Result<Vec<Val>, RuntimeError> {
    // do something
}

let my_func_type = FunctionType::new(vec![Type::I32], vec![Type::I32]);
let imports = imports!{
    "namespace" => {
        "my_func" => Function::new(&store, my_func_type, my_func),
    }
}

Note: Dynamic function trampolines are only compiled for imported function types.

Trait Implementations

impl Debug for Compilation

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Compilation

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Compilation

fn eq(&self, other: &Compilation) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for Compilation

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for Compilation

impl StructuralPartialEq for Compilation
