Struct colain::Loop [−][src]
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>
[src]
pub fn iter(&'a self) -> ArrayChunksCopy<'a, <T as CLIType>::Coord, 2>
[src]
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
[src]
Get the CLI ID of this primitive
pub fn dir(&self) -> <T as CLIType>::Meta
[src]
Get the direction of this loop
pub fn points(&'a self) -> &'a [<T as CLIType>::Coord]
[src]
Pointer into the segment of the file that contains this geometry
