• 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.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
