Struct ViewRequest 

pub struct ViewRequest {
    pub generation: u32,
    pub revision: u32,
    pub sequence: u32,
    pub bounds: [f64; 4],
    pub viewport: [f64; 2],
    pub action: ViewAction,
}

A geometry snapshot and source action with a generation-local ordering key.

Bounds use ordered finite minimum/maximum endpoints; viewport sizes are positive.

Examples

let request = ViewRequest { generation: 1, revision: 1, sequence: 1,
    bounds: [0.0, 0.0, 200.0, 100.0], viewport: [400.0, 300.0],
    action: ViewAction::Fit };
assert_eq!(request.sequence, 1);

Fields

generation: u32

The explicitly started lifecycle.

revision: u32

The geometry revision measured by the renderer.

sequence: u32

The strictly increasing generation-local submission number.

bounds: [f64; 4]

Minimum x/y followed by maximum x/y.

viewport: [f64; 2]

Positive viewport width and height.

action: ViewAction

The requested source operation.
