Struct SnapService 

pub struct SnapService { /* private fields */ }

Snap service for applying snap behavior to points

Implementations

impl SnapService

pub fn new() -> Self

Create a new snap service with default options

pub fn with_options(options: SnapOptions) -> Self

Create with custom options

pub fn options(&self) -> &SnapOptions

Get the current options

pub fn options_mut(&mut self) -> &mut SnapOptions

Get mutable options

pub fn snap_point(&self, point: Pos2, targets: &SnapTargets) -> Pos2

Apply snap to a point

Applies in order:

1. Snap to price (Y axis)
2. Snap to time (X axis)
3. Magnet mode (snap to nearest drawing point)

pub fn snap_point_with_drawing_points<I>( &self, point: Pos2, prices: &[f32], times: &[f32], drawing_points: I, ) -> Pos2

where I: IntoIterator<Item = Pos2>,

Apply snap to a point, sourcing magnet targets from a borrowed iterator.

Identical behavior to SnapService::snap_point, but the magnet-mode drawing points are supplied as an iterator rather than an owned Vec. This lets per-pointer-move callers (e.g. during a drag) borrow the live drawing geometry instead of cloning every point of every drawing on each pointer event. The iterator is only consumed when magnet mode is active.

pub fn would_snap(&self, point: Pos2, targets: &SnapTargets) -> bool

Check if a point would snap

Returns true if the point would be modified by snapping.

pub fn get_snap_indicator( &self, point: Pos2, targets: &SnapTargets, ) -> Option<Pos2>

Get snap indicator position if snapping is active

Returns the snapped position only if it differs from input, useful for showing snap indicators in the UI.

pub fn set_snap_to_price(&mut self, enabled: bool)

Enable/disable snap to price

pub fn set_snap_to_time(&mut self, enabled: bool)

Enable/disable snap to time

pub fn set_magnet_mode(&mut self, enabled: bool)

Enable/disable magnet mode

pub fn set_snap_distance(&mut self, distance: f32)

Set snap distance

pub fn set_magnet_distance(&mut self, distance: f32)

Set magnet distance
