Struct JsColor 

pub struct JsColor { /* private fields */ }

JavaScript-friendly wrapper for Color.

Implementations

impl JsColor

pub fn from_hex(hex: &str) -> Result<JsColor, JsValue>

Create a color from a hex string (e.g., “#ff00ff” or “ff00ff”).

This function currently always succeeds as color parsing is permissive.

pub fn from_rgb(r: u8, g: u8, b: u8) -> JsColor

Create a color from RGB values.

pub fn from_ansi(code: u8) -> JsColor

Create a color from an ANSI 256-color code.

pub fn to_hex(&self) -> String

Get the hex representation of this color.

Trait Implementations

impl Clone for JsColor

fn clone(&self) -> JsColor

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for JsColor

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

Formats the value using the given formatter.

impl FromWasmAbi for JsColor

type Abi = u32

The Wasm ABI type that this converts from when coming back out from the ABI boundary.

unsafe fn from_abi(js: u32) -> JsColor

Recover a Self from Self::Abi.

impl IntoWasmAbi for JsColor

type Abi = u32

The Wasm ABI type that this converts into when crossing the ABI boundary.

fn into_abi(self) -> u32

Convert self into Self::Abi so that it can be sent across the wasm ABI boundary.

impl LongRefFromWasmAbi for JsColor

type Abi = u32

Same as RefFromWasmAbi::Abi

type Anchor = RcRef<JsColor>

Same as RefFromWasmAbi::Anchor

unsafe fn long_ref_from_abi( js: <JsColor as LongRefFromWasmAbi>::Abi, ) -> <JsColor as LongRefFromWasmAbi>::Anchor

Same as RefFromWasmAbi::ref_from_abi

impl OptionFromWasmAbi for JsColor

fn is_none(abi: &<JsColor as FromWasmAbi>::Abi) -> bool

Tests whether the argument is a “none” instance. If so it will be deserialized as None, and otherwise it will be passed to FromWasmAbi.

impl OptionIntoWasmAbi for JsColor

fn none() -> <JsColor as IntoWasmAbi>::Abi

Returns an ABI instance indicating “none”, which JS will interpret as the None branch of this option.

impl RefFromWasmAbi for JsColor

type Abi = u32

The Wasm ABI type references to Self are recovered from.

type Anchor = RcRef<JsColor>

The type that holds the reference to Self for the duration of the invocation of the function that has an &Self parameter. This is required to ensure that the lifetimes don’t persist beyond one function call, and so that they remain anonymous.

unsafe fn ref_from_abi( js: <JsColor as RefFromWasmAbi>::Abi, ) -> <JsColor as RefFromWasmAbi>::Anchor

Recover a Self::Anchor from Self::Abi.

impl RefMutFromWasmAbi for JsColor

type Abi = u32

Same as RefFromWasmAbi::Abi

type Anchor = RcRefMut<JsColor>

Same as RefFromWasmAbi::Anchor

unsafe fn ref_mut_from_abi( js: <JsColor as RefMutFromWasmAbi>::Abi, ) -> <JsColor as RefMutFromWasmAbi>::Anchor

Same as RefFromWasmAbi::ref_from_abi

impl TryFromJsValue for JsColor

fn try_from_js_value(value: JsValue) -> Result<JsColor, JsValue>

Performs the conversion.

fn try_from_js_value_ref(value: &JsValue) -> Option<JsColor>

Performs the conversion.

impl VectorFromWasmAbi for JsColor

type Abi = <Box<[JsValue]> as FromWasmAbi>::Abi

unsafe fn vector_from_abi( js: <JsColor as VectorFromWasmAbi>::Abi, ) -> Box<[JsColor]>

impl VectorIntoWasmAbi for JsColor

type Abi = <Box<[JsValue]> as IntoWasmAbi>::Abi

fn vector_into_abi( vector: Box<[JsColor]>, ) -> <JsColor as VectorIntoWasmAbi>::Abi
