Enum TrapShape 

pub enum TrapShape {
    None,
    Point,
    Line,
    Cross,
    Circle,
}

Escape time only: the shape an orbit is measured against ([field] trap).

With a trap, a pixel is coloured by the smallest distance its orbit came to the shape rather than by how fast it escaped — which is what draws the filaments, rings and stained-glass cells of orbit-trap imagery. Each shape sits trap_radius from the origin, turned by trap_rotate.

Variants

None

No trap: the smooth escape count colours the picture.

Point

A point trap_radius from the origin along trap_rotate.

Line

A line trap_radius from the origin, its normal along trap_rotate.

Cross

Two perpendicular lines crossing at the point Point would sit at, turned by trap_rotate.

Circle

A circle of radius trap_radius about the origin; trap_rotate is inert on it.

Implementations

impl TrapShape

pub const ALL: [TrapShape; 5]

Every shape, in the order the shader’s trap index numbers them.

pub fn from_name(name: &str) -> Option<Self>

Parse the canonical [field] trap = "..." value, or None.

pub fn as_str(self) -> &'static str

The canonical name — from_name’s inverse.

Trait Implementations

impl Clone for TrapShape

fn clone(&self) -> TrapShape

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TrapShape

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

Formats the value using the given formatter.

impl Default for TrapShape

fn default() -> TrapShape

Returns the “default value” for a type.

impl PartialEq for TrapShape

fn eq(&self, other: &TrapShape) -> 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.
