Struct DiagnosticSupport 

pub struct DiagnosticSupport<E: DiagnosticRecord, H: DiagnosticHookDispatch<E>> { /* private fields */ }

Shared state for optional diagnostic logging plus optional telemetry hooks.

This is the reusable control-flow skeleton shared by diagnostic-enabled widgets and screens:

• optional bounded log
• optional hook collection
• shared record() ordering: hooks first, then log

Implementations

impl<E: DiagnosticRecord, H: DiagnosticHookDispatch<E>> DiagnosticSupport<E, H>

pub fn new() -> Self

Create an empty diagnostic support bundle with no log and no hooks.

pub fn with_log(self, log: DiagnosticLog<E>) -> Self

Enable logging with the provided diagnostic log.

pub fn with_hooks(self, hooks: H) -> Self

Enable telemetry hooks with the provided hook set.

pub fn set_log(&mut self, log: DiagnosticLog<E>)

Replace the diagnostic log.

pub fn set_hooks(&mut self, hooks: H)

Replace the telemetry hooks.

pub fn log(&self) -> Option<&DiagnosticLog<E>>

Borrow the diagnostic log, if enabled.

pub fn log_mut(&mut self) -> Option<&mut DiagnosticLog<E>>

Mutably borrow the diagnostic log, if enabled.

pub fn hooks(&self) -> Option<&H>

Borrow the telemetry hooks, if enabled.

pub fn is_active(&self) -> bool

Returns true when either logging or hooks are enabled.

pub fn record(&mut self, entry: E)

Dispatch an entry to hooks first, then record it to the log.
