Enum Blend

pub enum Blend {
    Linear,
    Nearest,
    None,
}

How a channel’s values may be combined when a new vertex appears.

This is a property of the DATA, not of the operation. An operation asks the channel what is permissible; it does not decide on the channel’s behalf.

Variants

Linear

Values are continuous and may be linearly interpolated.

Appropriate for texture coordinates, temperatures, displacements.

Nearest

Values are labels. A new vertex takes the value of the nearest existing one; averaging two ids would invent a third that names nothing.

None

Values cannot be derived for a vertex that did not exist before.

The channel is dropped rather than guessed at.

Trait Implementations

impl Clone for Blend

fn clone(&self) -> Blend

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Blend

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

Formats the value using the given formatter.

impl Hash for Blend

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Blend

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