Struct CollisionResolver 

pub struct CollisionResolver { /* private fields */ }

Collision resolver for subtitle positioning

Implementations

impl CollisionResolver

pub fn new(screen_width: f32, screen_height: f32) -> Self

Create a new collision resolver

pub fn clear(&mut self)

Clear all positioned events

pub fn set_collision_margin(&mut self, margin: f32)

Set collision margin

pub fn add_fixed(&mut self, event: PositionedEvent)

Add a positioned event that won’t be moved

pub fn find_position(&mut self, event: PositionedEvent) -> BoundingBox

Resolve collisions by stacking the event away from its alignment margin: bottom-aligned events (1-3) move up, top/middle (4-9) move down, until the event no longer overlaps any already-placed same-layer event. This matches libass “Normal” collisions, where earlier events keep the margin position and later events stack past them. The resolved box is recorded so that subsequent events stack against it.

pub fn positioned_events(&self) -> &[PositionedEvent]

Get all positioned events
