Struct js::jsapi::JSJitInfo

#[repr(C)]
pub struct JSJitInfo {
    pub call: *const c_void,
    pub protoID: u16,
    pub depth: u16,
    pub _bitfield_1: u32,
}

This struct contains metadata passed from the DOM to the JS Engine for JIT optimizations on DOM property accessors. Eventually, this should be made available to general JSAPI users, but we are not currently ready to do so.

Fields

call: *const c_void

protoID: u16

depth: u16

_bitfield_1: u32

The OpType that says what sort of function we are.
