Struct JsFunction

pub struct JsFunction { /* private fields */ }

Wraps an object from the QuickJs runtime. Provides convenience property accessors.

Implementations

impl JsFunction

pub fn try_from_value(value: OwnedJsValue) -> Result<Self, ValueError>

pub fn into_value(self) -> OwnedJsValue

pub fn call( &self, args: Vec<OwnedJsValue>, ) -> Result<OwnedJsValue, ExecutionError>

Methods from Deref<Target = OwnedJsValue>

pub fn context(&self) -> *mut JSContext

pub fn tag(&self) -> JsTag

pub unsafe fn as_inner(&self) -> &JSValue

Get the inner JSValue without increasing ref count.

Unsafe because the caller must ensure proper memory management.

pub fn is_null(&self) -> bool

Check if this value is null.

pub fn is_undefined(&self) -> bool

Check if this value is undefined.

pub fn is_bool(&self) -> bool

Check if this value is bool.

pub fn is_int(&self) -> bool

Check if this value is int.

pub fn is_bigint(&self) -> bool

Check if this value is BigInt.

pub fn is_short_bigint(&self) -> bool

Check if this value is BigInt, but short enough to fit in a i32

pub fn is_float(&self) -> bool

Check if this value is float.

pub fn is_exception(&self) -> bool

Check if this value is a Javascript exception.

pub fn is_object(&self) -> bool

Check if this value is a Javascript object.

pub fn is_array(&self) -> bool

Check if this value is a Javascript array.

pub fn is_function(&self) -> bool

Check if this value is a Javascript function.

pub fn is_promise(&self) -> bool

Check if this value is a Javascript promise.

pub fn is_module(&self) -> bool

Check if this value is a Javascript module.

pub fn is_string(&self) -> bool

Check if this value is a Javascript string.

pub fn is_compiled_function(&self) -> bool

Check if this value is a bytecode compiled function.

pub fn to_bool(&self) -> Result<bool, ValueError>

Convert this value into a bool

pub fn to_int(&self) -> Result<i32, ValueError>

Convert this value into an i32

pub fn to_float(&self) -> Result<f64, ValueError>

Convert this value into an f64

pub fn to_string(&self) -> Result<String, ValueError>

Convert this value into a string

pub fn to_array(&self) -> Result<OwnedJsArray, ValueError>

pub fn to_date(&self) -> Result<DateTime<Utc>, ValueError>

pub fn to_bigint(&self) -> Result<BigInt, ValueError>

pub fn js_to_string(&self) -> Result<String, ExecutionError>

Call the Javascript .toString() method on this value.

pub fn to_json_string(&self, space: u8) -> Result<String, ExecutionError>

Call the Javascript JSON.stringify() method on this value.

Trait Implementations

impl Clone for JsFunction

fn clone(&self) -> JsFunction

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for JsFunction

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

Formats the value using the given formatter.

impl Deref for JsFunction

type Target = OwnedJsValue

The resulting type after dereferencing.

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

Dereferences the value.

impl PartialEq for JsFunction

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

impl ToOwnedJsValue for JsFunction

fn to_owned(self, context: *mut JSContext) -> OwnedJsValue

impl TryFrom<OwnedJsValue> for JsFunction

type Error = ValueError

The type returned in the event of a conversion error.

fn try_from(value: OwnedJsValue) -> Result<Self, Self::Error>

Performs the conversion.
