Struct centerline::LineStringSet2

pub struct LineStringSet2<T: GenericVector2> {
    pub internals: Option<Vec<(Aabb2<T>, Vec<T>)>>,
    /* private fields */
}

A set of 2d LineString, an aabb + convex_hull. It also contains a list of aabb & convex_hulls of shapes this set has gobbled up. This can be useful for separating out inner regions of the shape.

This struct is intended to contain related shapes. E.g. outlines of letters with holes

Fields

internals: Option<Vec<(Aabb2<T>, Vec<T>)>>

Implementations

impl<T: GenericVector2> LineStringSet2<T>

pub fn steal_from(other: &mut LineStringSet2<T>) -> Self

steal the content of ‘other’ leaving it empty

pub fn set(&self) -> &Vec<Vec<T>>

pub fn with_capacity(capacity: usize) -> Self

pub fn get_internals(&self) -> Option<&Vec<(Aabb2<T>, Vec<T>)>>

pub fn is_empty(&self) -> bool

pub fn push(&mut self, ls: Vec<T>)

pub fn get_convex_hull(&self) -> &Option<Vec<T>>

returns the combined convex hull of all the shapes in self.set

pub fn calculate_convex_hull(&mut self) -> Result<&Vec<T>, LinestringError>

calculates the combined convex hull of all the shapes in self.set

pub fn get_aabb(&self) -> Aabb2<T>

Returns the axis aligned bounding box of this set.

pub fn copy_to_3d(&self, plane: Plane) -> LineStringSet3<T::Vector3>

Copy this linestringset2 into a linestringset3, populating the axes defined by ‘plane’ An axis will always try to keep it’s position (e.g. y goes to y if possible). That way the operation is reversible (with regards to axis positions). The empty axis will be set to zero.

pub fn take_from(&mut self, other: Self)

drains the ‘other’ container of all shapes and put them into ‘self’

pub fn take_from_internal( &mut self, other: &mut Self ) -> Result<(), LinestringError>

drains the ‘other’ container of all shapes and put them into ‘self’ The other container must be entirely ‘inside’ the convex hull of ‘self’ The ‘other’ container must also contain valid ‘internals’ and ‘convex_hull’ fields

pub fn apply<F: Fn(T) -> T>(&mut self, f: &F)

Apply an operation over each coordinate in the contained objects. Useful when you want to round the value of each contained coordinate.

Trait Implementations

impl<T: Clone + GenericVector2> Clone for LineStringSet2<T>

fn clone(&self) -> LineStringSet2<T>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<T: GenericVector2> Default for LineStringSet2<T>

fn default() -> Self

Returns the “default value” for a type.
