Struct DecodeParams 

#[non_exhaustive]
pub struct DecodeParams {
    pub predictor: u16,
    pub colors: u16,
    pub bits_per_component: u16,
    pub columns: u32,
    pub early_change: u8,
    pub crypt_filter_name: Option<PdfName>,
}

Structured parameters for one stream filter.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

predictor: u16

Predictor algorithm, where 1 means no predictor.

colors: u16

Number of colour components for predictor decoding.

bits_per_component: u16

Bits per component for predictor decoding.

columns: u32

Predictor column count.

early_change: u8

LZW early-change mode.

crypt_filter_name: Option<PdfName>

Named crypt filter, when /Filter /Crypt carries one.

Trait Implementations

impl Clone for DecodeParams

fn clone(&self) -> DecodeParams

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DecodeParams

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

Formats the value using the given formatter.

impl Default for DecodeParams

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for DecodeParams

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for DecodeParams

fn eq(&self, other: &DecodeParams) -> 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 Serialize for DecodeParams

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for DecodeParams

impl StructuralPartialEq for DecodeParams
