Struct FunctionOptions 

pub struct FunctionOptions {
    pub name: String,
    pub length: u32,
    pub constructor: bool,
    pub data: Vec<Value>,
}

How a host function is made: its name and length, whether new may call it, and the values it captures (Scope::data). Captured values are traced by the collector; a Rust value the closure captures is not.

Fields

name: String

length: u32

constructor: bool

data: Vec<Value>

Implementations

impl FunctionOptions

pub fn new(name: impl Into<String>) -> Self

pub fn length(self, length: u32) -> Self

pub fn constructor(self) -> Self

The function may be called by new (Scope::is_construct). It has no prototype property until the embedder defines one.

pub fn data(self, data: Vec<Value>) -> Self

Trait Implementations

impl Clone for FunctionOptions

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FunctionOptions

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

Formats the value using the given formatter.

impl Default for FunctionOptions

fn default() -> Self

Returns the “default value” for a type.
