Enum DepthPolicy 

#[non_exhaustive]
pub enum DepthPolicy {
    Round,
    Truncate,
    Forbid,
}

Policy for bit depth reduction (U16→U8, etc.).

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Round

Round to nearest value.

Truncate

Truncate (floor). Faster, biased toward lower values.

Forbid

Return error rather than reducing depth.

Trait Implementations

impl Clone for DepthPolicy

fn clone(&self) -> DepthPolicy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DepthPolicy

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

Formats the value using the given formatter.

impl Hash for DepthPolicy

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

where __H: Hasher,

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 DepthPolicy

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