Implementations

impl FunctionType

pub fn new(params: Array<Type>, results: Array<Type>) -> Self

Creates a new FunctionType.

Example

    [Wasmer::Type::I32, Wasmer::Type::I64],
    [Wasmer::Type::I32]
)

pub fn params(&self) -> Array<Type>

Returns the parameters.

Example

function_type = Wasmer::FunctionType.new(
    [Wasmer::Type::I32, Wasmer::Type::I64],
    [Wasmer::Type::I32]
)

assert { function_type.params == [Wasmer::Type::I32, Wasmer::Type::I64] }

pub fn results(&self) -> Array<Type>

Returns the results.

Example

function_type = Wasmer::FunctionType.new(
    [Wasmer::Type::I32, Wasmer::Type::I64],
    [Wasmer::Type::I32]
)

assert { function_type.results == [Wasmer::Type::I32] }
