Struct v8::Signature

#[repr(C)]
pub struct Signature(_);

A Signature specifies which receiver is valid for a function.

A receiver matches a given signature if the receiver (or any of its hidden prototypes) was created from the signature’s FunctionTemplate, or from a FunctionTemplate that inherits directly or indirectly from the signature’s FunctionTemplate.

Implementations

impl Signature

A Signature specifies which receiver is valid for a function.

A receiver matches a given signature if the receiver (or any of its hidden prototypes) was created from the signature’s FunctionTemplate, or from a FunctionTemplate that inherits directly or indirectly from the signature’s FunctionTemplate.

pub fn new<'s>(
    scope: &mut HandleScope<'s, ()>,
    templ: Local<'_, FunctionTemplate>
) -> Local<'s, Self>

Trait Implementations

impl Debug for Signature

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

Formats the value using the given formatter.

impl Deref for Signature

type Target = Data

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl<'s> PartialEq<Data> for Signature

fn eq(&self, other: &Data) -> 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<'s> PartialEq<Signature> for Data

fn eq(&self, other: &Signature) -> 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<'s> PartialEq<Signature> for Signature

fn eq(&self, other: &Signature) -> 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.
