Enum ModifierFamily 

#[non_exhaustive]
pub enum ModifierFamily {
    Exact,
    BroadcomSand {
        code: u64,
    },
}

The family a modifier belongs to, for eligibility matching.

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.

Exact

The modifier matches only itself. Everything not named below.

BroadcomSand

Broadcom SAND, one of SAND64 / SAND128 / SAND256.

The low byte is the layout code; bits 8..56 carry the column height. A plane advertises the base (column height 0); a producer bakes the coded image height in. rpi-hevc-dec exporting SAND128 with the column height set is the case PR #231 fixed.

SAND32 (code 2) is deliberately not a member: the upstream commit names SAND64/128/256 explicitly, and widening the range here would be a behavior change with no driver evidence behind it.

Fields

code: u64

The SAND layout code: 3, 4, or 5.

Implementations

impl ModifierFamily

pub const fn base(self) -> Option<Modifier>

The base modifier a plane advertises for this family, if the family is parameterized.

ModifierFamily::Exact has no base — such a modifier is only ever eligible against itself.

Trait Implementations

impl Clone for ModifierFamily

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ModifierFamily

impl Debug for ModifierFamily

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

Formats the value using the given formatter.

impl Eq for ModifierFamily

impl Hash for ModifierFamily

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 Ord for ModifierFamily

fn cmp(&self, other: &Self) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

where Self: Sized,

Restrict a value to a certain interval.

fn clamp_to<R>(self, range: R) -> Self

where Self: Sized, R: ClampBounds<Self>,

🔬This is a nightly-only experimental API. (clamp_to)

Restrict a value to a certain range.

impl PartialEq for ModifierFamily

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for ModifierFamily

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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