ducc-sys

Low-level Duktape FFI for the ducc crate.

Helper extensions

This FFI exposes all of the stock Duktape items (all prefixed with duk_ or DUK_). In addition to these items, the FFI also offers helper extensions specifically for dealing with Duktape from Rust. These are all prefixed with ducc_ and are listed below:

ducc_push_c_function_nothrow

Like duk_push_c_function, but negative values from func are handled differently. Instead of being able to return DUK_RET_xxx, func can return -1 (all negatively values are handled the same currently) to have an error object pushed to the top of the stack be thrown.

When func returns a non-negative integer, this function is handled equivalent to how it is handled with duk_push_c_function.

This function assigns a hidden property named "__NOTHROWFUNC" on the newly created function (DUK_HIDDEN_SYMBOL("__NOTHROWFUNC")).

ducc_set_exec_timeout_function

Sets the global timeout callback. This should be set only once per application, as it is shared between all contexts. See DUK_USE_EXEC_TIMEOUT_CHECK for more information on how this callback should function.

Execution timeout are only enabled if the use-exec-timeout-check Cargo feature is set.

ducc_exec_timeout_function

The callback type for duk_set_exec_timeout_function.
