Implementations

impl ViewLib

pub fn install() -> Result<Self, Error>

Extract the embedded library to the temp directory and link to it.

pub fn uninstall() -> Result<bool, Error>

Try to delete the installed library from the temp directory.

See uninstall_from for details.

pub fn install_to(dir: impl Into<PathBuf>) -> Result<Self, Error>

Extract the embedded library to dir and link to it.

pub fn uninstall_from(dir: impl Into<PathBuf>) -> Result<bool, Error>

Try to delete the installed library from the given dir.

Returns Ok(true) if uninstalled, Ok(false) if was not installed and Err(_) if is installed and failed to delete.

Note that the file is probably in use if it was installed in the current process instance, in Windows files cannot be deleted until they are released.

pub fn link(view_dylib: impl Into<PathBuf>) -> Result<Self, Error>

Link to the pre-built library file.

If the file does not have an extension searches for a file without extension then a .dll file in Windows, a .so file in Linux and a .dylib file in other operating systems.

Note that the is only searched as described above, if it is not found an error returns immediately, the operating system library search feature is not used.

pub fn view_process_main(self)

Call the pre-built view_process_main.

Aborts

Kills the process with code 101 if there is a panic generated by the pre-built code or by threads started by the pre-build code, this needs to happen because unwind across FFI in undefined behavior.

pub fn run_same_process(self, run_app: impl FnOnce() + Send + 'static) -> !

Call the pre-build run_same_process.

This function exits the process after run_app returns.

Aborts

Kills the process with code 101 if there is a panic generated by the pre-built code or by threads started by the pre-build code, this needs to happen because unwind across FFI in undefined behavior.
