Struct GpuConfig 

#[non_exhaustive]
pub struct GpuConfig {
    pub label: &'static str,
    pub copy_src: CopySrc,
    pub present_mode: PresentMode,
}

Everything Gpu::new needs beyond the window handle.

Build one with GpuConfig::new (or Default) and the with_* setters rather than a struct literal — the struct is #[non_exhaustive] so new knobs can be added without a breaking release:

use agg_gui_wgpu::{CopySrc, GpuConfig};
let cfg = GpuConfig::new("my-app").with_copy_src(CopySrc::IfSupported);

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

label: &'static str

wgpu::DeviceDescriptor label — shows up in backend validation messages and GPU captures, so each shell names its own.

copy_src: CopySrc

Surface read-back requirement, see CopySrc.

present_mode: PresentMode

Present mode for the swap chain. AutoVsync for normal windows.

Implementations

impl GpuConfig

pub fn new(label: &'static str) -> Self

Default configuration under a shell-specific device label.

pub fn with_copy_src(self, copy_src: CopySrc) -> Self

pub fn with_present_mode(self, present_mode: PresentMode) -> Self

Override the swap-chain present mode (default AutoVsync).
