Source §

impl SpeculativePrefetcher

Source

pub fn new(prediction_window_secs: f64, cache_capacity: usize) -> Self

Source

pub fn update_position(&mut self, current_center_time: f64)

Actualiza el estado de navegación según la posición actual del viewport. Calcula la velocidad $\vec{v} = \frac{\Delta x}{\Delta t}$ e inercia.

Source

pub fn current_velocity(&self) -> f64

Obtiene la velocidad actual estimada del desplazamiento.

Source

pub fn predict_future_range(&self, current_span: f64) -> (f64, f64)

Calcula la posición futura predecida $T_{\text{futuro}} = T_{\text{actual}} + \vec{v} \cdot \Delta t_{\text{preview}}$.

Source

pub fn prefetch_mmap( &mut self, reader: &MmapReader, offset_bytes: usize, length_bytes: usize, ) -> Result<()>
