Struct ParamsAccessor

Source 
pub struct ParamsAccessor<'a, 'js> { /* private fields */ }
Expand description

Accessor to parameters used for retrieving arguments in order one at the time.

Implementations§

Source§

impl<'a, 'js> ParamsAccessor<'a, 'js>

Source

pub fn ctx(&self) -> &Ctx<'js>

Returns the context associated with the params.

Source

pub fn this(&self) -> Value<'js>

Returns this value of call from which the params originate.

Source

pub fn function(&self) -> Value<'js>

Returns the value on which this function called. i.e. in bla.foo() the foo value.

Source

pub fn arg(&mut self) -> Value<'js>

Returns the next arguments.

Each call to this function returns a different argument

§Panic

This function panics if it is called more times then there are arguments.

Source

pub fn len(&self) -> usize

returns the number of arguments remaining

Source

pub fn is_empty(&self) -> bool

returns whether there are any arguments remaining.
