Struct GuestFunctionDefinition 

pub struct GuestFunctionDefinition {
    pub function_name: String,
    pub parameter_types: Vec<ParameterType>,
    pub return_type: ReturnType,
    pub function_pointer: usize,
}

The definition of a function exposed from the guest to the host

Fields

function_name: String

The function name

parameter_types: Vec<ParameterType>

The type of the parameter values for the host function call.

return_type: ReturnType

The type of the return value from the host function call

function_pointer: usize

The function pointer to the guest function

Implementations

impl GuestFunctionDefinition

pub fn new( function_name: String, parameter_types: Vec<ParameterType>, return_type: ReturnType, function_pointer: usize, ) -> Self

Create a new GuestFunctionDefinition.

pub fn verify_parameters(&self, parameter_types: &[ParameterType]) -> Result<()>

Verify that self has same signature as the provided parameter_types.

Trait Implementations

impl Clone for GuestFunctionDefinition

fn clone(&self) -> GuestFunctionDefinition

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for GuestFunctionDefinition

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

Formats the value using the given formatter.

impl PartialEq for GuestFunctionDefinition

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

Tests for self and other values to be equal, and is used by ==.

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

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