Struct TemplateHooks 

pub struct TemplateHooks { /* private fields */ }

Container for registered template event hooks.

Implementations

impl TemplateHooks

pub fn new() -> Self

Creates a new empty hook container.

pub fn register<F>(&mut self, hook: F)

where F: Fn(&TemplateEvent) -> Result<(), TemplateHookError> + Send + Sync + 'static,

Registers a new hook.

pub fn clear(&mut self)

Removes all registered hooks.

pub fn trigger(&mut self, event: &TemplateEvent)

Triggers all registered hooks with the given event.

All hooks are called regardless of whether earlier hooks return errors or panic. Errors and panics from hooks are isolated and do not interrupt other hooks or parsing. The error count is tracked via hook_error_count for production observability.

pub fn hook_error_count(&self) -> u64

Returns the total number of hook errors and panics encountered.

pub fn len(&self) -> usize

Returns the number of registered hooks.

pub fn is_empty(&self) -> bool

Returns true if no hooks are registered.
