Enum FormatCategory 

#[non_exhaustive]
pub enum FormatCategory {
    Packed,
    Planar420,
    SemiPlanar420,
}

Category of pixel format for buffer calculation and union field access.

This enum distinguishes between different memory layouts:

• Packed: All pixel components are interleaved in a single buffer
• Planar420: Y, U, V planes stored separately with 4:2:0 chroma subsampling
• SemiPlanar420: Y plane followed by interleaved UV plane (NV12)

This enum is marked #[non_exhaustive] because the NDI SDK’s video FourCC namespace is open and grows across releases; future formats may introduce additional memory-layout categories.

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.

Packed

Packed formats: simple stride * height buffer.

Planar420

Planar 4:2:0 with separate U and V planes (YV12, I420).

SemiPlanar420

Semi-planar 4:2:0 with interleaved UV plane (NV12).

Trait Implementations

impl Clone for FormatCategory

fn clone(&self) -> FormatCategory

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FormatCategory

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

Formats the value using the given formatter.

impl PartialEq for FormatCategory

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