Enum RoundMode

pub enum RoundMode {
    Grid,

    Super,

}

Rounding strategies supported by the interpreter.

Variants

Grid

Distances are rounded to the closest grid line.

Set by RTG instruction.

HalfGrid

Distances are rounded to the nearest half grid line.

Set by RTHG instruction.

DoubleGrid

Distances are rounded to the closest half or integer pixel.

Set by RTDG instruction.

DownToGrid

Distances are rounded down to the closest integer grid line.

Set by RDTG instruction.

UpToGrid

Distances are rounded up to the closest integer pixel boundary.

Set by RUTG instruction.

Off

Rounding is turned off.

Set by ROFF instruction.

Super

Allows fine control over the effects of the round state variable by allowing you to set the values of three components of the round_state: period, phase, and threshold.

More formally, maps the domain of 26.6 fixed point numbers into a set of discrete values that are separated by equal distances.

Set by SROUND instruction.

Super45

Analogous to Super. The grid period is sqrt(2)/2 pixels rather than 1 pixel. It is useful for measuring at a 45 degree angle with the coordinate axes.

Set by S45ROUND instruction.

Trait Implementations

impl Clone for RoundMode

fn clone(&self) -> RoundMode

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for RoundMode

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for RoundMode

fn default() -> RoundMode

Returns the “default value” for a type.

impl PartialEq for RoundMode

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

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Copy for RoundMode

impl Eq for RoundMode

impl StructuralPartialEq for RoundMode
