Implementations§

source§

impl PenCommand

source

pub fn apply_to<T: Pen>(&self, pen: &mut T)

source

pub fn end_point(&self) -> Option<(f32, f32)>

The directly stated - not implied - end point of the command.

Notably, Close does have an end point but it is not directly stated so it returns None.

impl PartialEq<PenCommand> for PenCommand

source§

fn eq(&self, other: &PenCommand) -> bool
