Struct BridgeState 

pub struct BridgeState { /* private fields */ }

Owns one cached model and lifecycle/order watermarks for one container.

Examples

let mut bridge = adam_web_ui::graph::BridgeState::default();
bridge.start(1)?;
assert!(bridge.start(1).is_err());

Implementations

impl BridgeState

pub fn process(&mut self, message: ViewMessage) -> Result<Option<ViewReply>>

Dispatches a typed lifecycle message without framework-specific branching.

Errors

Returns startup errors; current update failures are explicit failed replies.

• Complexity: O(p) time and space in model construction/propagation work.

Examples

use adam_web_ui::graph::{BridgeState, ViewMessage};
assert!(BridgeState::default().process(ViewMessage::Start { generation: 1 })?.is_none());

pub fn start(&mut self, generation: u32) -> Result<()>

Claims a strictly newer generation and parses its model exactly once.

Errors

Returns an error for a repeated/older generation or model initialization failure. A failed initialization still retires the claimed generation.

• Complexity: O(p) time and space for model initialization work p.

Examples

let mut bridge = adam_web_ui::graph::BridgeState::default();
bridge.start(1)?;

pub fn handle(&mut self, request: ViewRequest) -> Result<Option<ViewReply>>

Evaluates current ordered work without implicitly starting a generation.

Returns None only for inactive/unknown generations, consumed sequences, or older geometry. Invalid current inputs produce a Failed reply. Failed current requests consume their ordering identity too.

Errors

Reserves transport-level errors for the channel owner; model/input errors are represented by ViewReply::Failed.

• Complexity: O(p) time and space in cached model propagation work p.

Examples

let mut bridge = BridgeState::default();
assert!(bridge.handle(ViewRequest { generation: 1, revision: 1, sequence: 1,
    bounds: [0.0, 0.0, 1.0, 1.0], viewport: [100.0, 100.0],
    action: ViewAction::Fit })?.is_none());

pub fn dispose(&mut self, generation: u32)

Retires only the matching generation, retaining its terminal watermark.

Examples

let mut bridge = adam_web_ui::graph::BridgeState::default();
bridge.start(1)?;
bridge.dispose(1);
assert!(bridge.start(1).is_err());

Trait Implementations

impl Default for BridgeState

fn default() -> BridgeState

Returns the “default value” for a type.
