Enum Present 

pub enum Present {
    Glow,
    Solid,
}

[voxel] present — how the march draws a live cell (ADR-0269).

Variants

Glow

Every cell emits and absorbs; the ray runs on through the volume.

Solid

The ray stops at the first live cell and shades its face under one camera-space key light and an ambient term. The decay stages in front of it still glow.

Implementations

impl Present

pub const ALL: [Present; 2]

Every present, in the order the reference lists them.

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

The name a preset writes.

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

The present name spells, or None for a name outside the roster.

Trait Implementations

impl Clone for Present

fn clone(&self) -> Present

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Present

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

Formats the value using the given formatter.

impl Default for Present

fn default() -> Present

Returns the “default value” for a type.

impl PartialEq for Present

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