Updated src/gpu_page/imp.rs:

derenv · derenv · commit 882c0e31ce57 · 2024-05-20T20:56:37.000+01:00
- Updated reuse copyright year - Added clearer import headers - Refactored to now import std::cell::OnceCell as it has been [merged into std](rust-lang/rust#105587) - Refactored to now import std::sync::OncelLock as it has been [merged into std](rust-lang/rust#105587) - Refactored to import Value and ToValue from glib::value as it now has its own module in glib - Refactored to import Variant and FromVariant from glib::variant as it now has its own module in glib - Added glib::ControlFlow::Continue import - Updated "create_updater()" function to reflect glib::ControlFlow::Continue changes - Removed an unsafe block of code from "create_updater()" function - Refactored "constructed()" function to get "obj" reference via "self" instead of as a parameter - Updated "parent_constructed()" call in "constructed()" function - Refactored "properties()" and "signals()" functions to reflect OnceLock changes - Removed now unused "_obj" parameter to "property()" and "set_property()" functions Updated src/gpu_page/mod.rs: - Updated reuse copyright year - Added clearer import headers - Updated "new()" function to use "Object::builder::<GpuPage>().build()" instead of untyped "Obect::new()"" Signed-off-by: Deren Vural <35734401+derenv@users.noreply.github.com>
