Enum Predictor 

#[non_exhaustive]
#[repr(u16)]
pub enum Predictor {
    None = 1,
    Horizontal = 2,
    FloatingPoint = 3,
}

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.

None = 1

No changes were made to the data

Horizontal = 2

The images’ rows were processed to contain the difference of each pixel from the previous one.

This means that instead of having in order [r1, g1. b1, r2, g2 ...] you will find [r1, g1, b1, r2-r1, g2-g1, b2-b1, r3-r2, g3-g2, ...]

FloatingPoint = 3

Implementations

impl Predictor

pub const fn from_u16(val: u16) -> Option<Self>

pub const fn to_u16(&self) -> u16

Trait Implementations

impl Clone for Predictor

fn clone(&self) -> Predictor

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Predictor

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

Formats the value using the given formatter.

impl Hash for Predictor

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 Predictor

fn eq(&self, other: &Predictor) -> 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 TiffValue for Predictor

const BYTE_LEN: u8 = <u16 as TiffValue>::BYTE_LEN

const FIELD_TYPE: Type = Type::SHORT

fn count(&self) -> usize

fn data(&self) -> Cow<'_, [u8]>

Access this value as an contiguous sequence of bytes. If their is no trivial representation, allocate it on the heap.

fn bytes(&self) -> usize

fn write<W: Write>(&self, writer: &mut TiffWriter<W>) -> TiffResult<()>

Write this value to a TiffWriter. While the default implementation will work in all cases, it may require unnecessary allocations. The written bytes of any custom implementation MUST be the same as yielded by self.data().
