Rust-bindings for the PocketBook InkView library

Setup

Clone https://github.com/pocketbook/SDK_6.3.0/tree/5.19 and set it up as described.

Set target and library directory via .cargo/config, replacing $SDK_ROOT_DIR accordingly:

[build]
target = "arm-unknown-linux-gnueabi"

[target.arm-unknown-linux-gnueabi]
linker = "$SDK_ROOT_DIR/SDK-B288/usr/bin/arm-obreey-linux-gnueabi-clang"
rustflags = [
	"-C", "target-cpu=cortex-a7",
	"-L", "$SDK_ROOT_DIR/SDK-B288/usr/arm-obreey-linux-gnueabi/sysroot/usr/local/lib/"
]

Set environment variables for bindgen, replacing $SDK_ROOT_DIR accordingly:

$ export BINDGEN_EXTRA_CLANG_ARGS="--sysroot=$SDK_ROOT_DIR/SDK-B288/usr/arm-obreey-linux-gnueabi/sysroot/ -I$SDK_ROOT_DIR/SDK-B288/usr/arm-obreey-linux-gnueabi/sysroot/usr/include/freetype2"

Building

For build with debugging info:

$ cargo build --release

For optimized build:

$ RUSTFLAGS="-C link-arg=-s" cargo build --release

Using

Add inkview as dependency to your Crate.toml:

[dependencies]
inkview = { path = "path/to/inkview", version = "0.1" }

Please add license

I want to use your bindings in my rust pocketbook game. Please add a license so I can do this

Question regarding the implementation of more functions

Hey,

thanks for the binding. :)
When I want to use a function that is currently not in the lib.rs (e.g. DrawString), should I implement it into the file or use the plain c_api?

pub fn draw_string(x: i32, y: i32, s: &str) {
		let c_str = CString::new(s).expect("CString::new failed");
	unsafe {
		c_api::DrawString(x,y,c_str.as_ptr());
	}
}

Regarding the font functions --> do I need to call the close_font function to free the pointer or how does this work regarding C and Rust? Can you tell me how inkview handles this internally?

pub fn open_font(name: &str, size: i32, aa: i32) -> *mut c_api::ifont_s {
	let c_str = CString::new(name).expect("CString::new failed");
	unsafe {
		c_api::OpenFont(c_str.as_ptr(),size,aa)
	}
}

pub fn set_font(font: *const c_api::ifont_s, color: Color) {
	unsafe{
		c_api::SetFont(font, color.0)
	}
}

pub fn close_font(f: *mut c_api::ifont_s) {
	unsafe{
		c_api::CloseFont(f);
	} 
}

Thanks in advance 👍
