Struct x11rb::protocol::xproto::GcontextWrapper

pub struct GcontextWrapper<C: RequestConnection>(/* private fields */);

A RAII-like wrapper around a Gcontext.

Instances of this struct represent a Gcontext that is freed in Drop.

Any errors during Drop are silently ignored. Most likely an error here means that your X11 connection is broken and later requests will also fail.

Implementations

impl<C: RequestConnection> GcontextWrapper<C>

pub fn for_gcontext(conn: C, id: Gcontext) -> Self

Assume ownership of the given resource and destroy it in Drop.

pub fn gcontext(&self) -> Gcontext

Get the XID of the wrapped resource

pub fn into_gcontext(self) -> Gcontext

Assume ownership of the XID of the wrapped resource

This function destroys this wrapper without freeing the underlying resource.

impl<'c, C: X11Connection> GcontextWrapper<&'c C>

pub fn create_gc_and_get_cookie( conn: &'c C, drawable: Drawable, value_list: &CreateGCAux ) -> Result<(Self, VoidCookie<'c, C>), ReplyOrIdError>

Create a new Gcontext and return a Gcontext wrapper and a cookie.

This is a thin wrapper around create_gc that allocates an id for the Gcontext. This function returns the resulting GcontextWrapper that owns the created Gcontext and frees it in Drop. This also returns a VoidCookie that comes from the call to create_gc.

Errors can come from the call to X11Connection::generate_id or create_gc.

impl<C: X11Connection> GcontextWrapper<C>

pub fn create_gc( conn: C, drawable: Drawable, value_list: &CreateGCAux ) -> Result<Self, ReplyOrIdError>

Create a new Gcontext and return a Gcontext wrapper

This is a thin wrapper around create_gc that allocates an id for the Gcontext. This function returns the resulting GcontextWrapper that owns the created Gcontext and frees it in Drop.

Errors can come from the call to X11Connection::generate_id or create_gc.
