Struct LayoutDebugger 

pub struct LayoutDebugger { /* private fields */ }

Layout constraint debugger.

Collects layout solve records for introspection. Thread-safe via internal synchronization; can be shared across the application.

Supports optional telemetry hooks for external observability (bd-32my.5).

Implementations

impl LayoutDebugger

pub fn new() -> Arc<Self>

Create a new debugger wrapped in Arc (disabled by default).

pub fn set_telemetry_hooks(&self, hooks: LayoutTelemetryHooks)

Attach telemetry hooks for external observability.

pub fn clear_telemetry_hooks(&self)

Remove telemetry hooks.

pub fn enabled(&self) -> bool

Check if debugging is enabled.

pub fn set_enabled(&self, enabled: bool)

Enable or disable debugging.

pub fn toggle(&self) -> bool

Toggle debugging on/off.

pub fn clear(&self)

Clear all recorded data.

pub fn record(&self, record: LayoutRecord)

Record a flex layout solve.

Also fires telemetry hooks if attached:

• on_layout_solve for every recorded layout
• on_overflow if overflow detected
• on_underflow if underflow detected

pub fn record_grid(&self, record: GridLayoutRecord)

Record a grid layout solve.

Also fires telemetry hooks if attached.

pub fn snapshot(&self) -> Vec<LayoutRecord>

Get a snapshot of all flex layout records.

pub fn snapshot_grids(&self) -> Vec<GridLayoutRecord>

Get a snapshot of all grid layout records.

pub fn overflows(&self) -> Vec<LayoutRecord>

Get records with overflow conditions.

pub fn underflows(&self) -> Vec<LayoutRecord>

Get records with underflow conditions.

pub fn report(&self) -> String

Generate a summary report of all recorded layouts.

pub fn export_dot(&self) -> String

Export to Graphviz DOT format for visualization.

Each layout becomes a node, with edges representing parent-child relationships (if parent_index is set).

Trait Implementations
