Function js::jsapi::JS_GetTypedArrayLength [−] [src]

pub unsafe extern "C" fn JS_GetTypedArrayLength(obj: *mut JSObject) -> u32

Return the number of elements in a typed array.

|obj| must have passed a JS_IsTypedArrayObject/JS_Is*Array test, or somehow be known that it would pass such a test: it is a typed array or a wrapper of a typed array, and the unwrapping will succeed.

Search Tricks

Prefix searches with a type followed by a colon (e.g. fn:) to restrict the search to a given type.

Accepted types are: fn, mod, struct, enum, trait, type, macro, and const.

Search functions by type signature (e.g. vec -> usize or * -> vec)
