Enum Field

#[non_exhaustive]
#[repr(u32)]
pub enum Field {
    Any = 0,
    None = 1,
    Top = 2,
    Bottom = 3,
    Interlaced = 4,
    SequentialTb = 5,
    SequentialBt = 6,
    Alternate = 7,
    InterlacedTb = 8,
    InterlacedBt = 9,
}

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.

Any = 0

Driver can choose from none, top, bottom, interlaced depending on whatever it thinks is approximate

None = 1

This device has no fields

Top = 2

Top field only

Bottom = 3

Bottom field only

Interlaced = 4

Both fields interlaced

SequentialTb = 5

Both fields sequential into one buffer, top-bottom order

SequentialBt = 6

Same as above + bottom-top order

Alternate = 7

Both fields alternating into separate buffers

InterlacedTb = 8

Both fields interlaced, top field first and the top field is transmitted first

InterlacedBt = 9

Both fields interlaced, top field first and the bottom field is transmitted first

Trait Implementations

impl AsRef<u32> for Field

fn as_ref(&self) -> &u32

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for Field

fn clone(&self) -> Field

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Field

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

Formats the value using the given formatter.

impl Deref for Field

type Target = u32

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl Display for Field

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

Formats the value using the given formatter.

impl From<Field> for u32

fn from(data: Field) -> Self

Converts to this type from the input type.

impl PartialEq for Field

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

impl TryFrom<u32> for Field

type Error = u32

The type returned in the event of a conversion error.

fn try_from(data: u32) -> Result<Self, Self::Error>

Performs the conversion.

impl Copy for Field

impl Eq for Field

impl StructuralPartialEq for Field
