Struct wasmtime_environ::FunctionType

pub struct FunctionType {
    pub signature: SignatureIndex,
    pub func_ref: FuncRefIndex,
}

Type information about functions in a wasm module.

Fields

signature: SignatureIndex

The type of this function, indexed into the module-wide type tables for a module compilation.

func_ref: FuncRefIndex

The index into the funcref table, if present. Note that this is reserved_value() if the function does not escape from a module.

Implementations

impl FunctionType

pub fn is_escaping(&self) -> bool

Returns whether this function’s type is one that “escapes” the current module, meaning that the function is exported, used in ref.func, used in a table, etc.

Trait Implementations

impl Debug for FunctionType

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for FunctionType

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for FunctionType

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

Serialize this value into the given Serde serializer.
