Struct colain::Loop

pub struct Loop<'a, T: CLIType> { /* private fields */ }

Object representing a loop inside of a Layer

Each Loop contains an id (see the spec for uses), a direction and a slice pointer to the geometry data.

According to the spec, the direction could be one of 3 values. However, it is left as an integer since some slicers interpret these values differently. According to the spec the direction can be:

• 0 : clockwise (internal)
• 1 : counter-clockwise (external)
• 2 : open line (no solid)

Each point is stored as an array of length two of the CLIType’s associated Coord type. The Point trait is provided as a more elegant way to access the data.

Implementations

impl<'a, T: CLIType> Loop<'a, T>

pub fn iter(&'a self) -> ArrayChunksCopy<'a, <T as CLIType>::Coord, 2>

Iterate over each point in the loop as [T; 2]

Note availability of Point trait for a cleaner interface

pub fn id(&self) -> <T as CLIType>::Meta

Get the CLI ID of this primitive

pub fn dir(&self) -> <T as CLIType>::Meta

Get the direction of this loop

pub fn points(&'a self) -> &'a [<T as CLIType>::Coord]

Pointer into the segment of the file that contains this geometry
