• a:
• b:
• c:

returns: Triangle

Examples

Required Associated Types

type Value

The value type of the shape.

type VertexIterator<'a>: Iterator<Item = Point<Self::Value>> where Self: 'a

The value type of the shape.

type LineIterator<'a>: Iterator<Item = Line<Self::Value>> where Self: 'a

The value type of the shape.

Required Methods

fn is_valid(&self) -> bool

Returns true if the shape is valid and in normal form.

fn boundary(&self) -> Rectangle<Self::Value>

Returns the boundary of the shape.

fn vertices<'a>(&'a self, sample: usize) -> Self::VertexIterator<'a>

Returns the owned vertices of the shape.

Notice that sample only works for non-linear shapes.

fn edges<'a>(&'a self, sample: usize) -> Self::LineIterator<'a>

Returns the owned edges of the shape.

Provided Methods

fn normalize(&mut self) -> bool

Returns true if the shape successfully normalized.

Object Safety

This trait is not object safe.
