Struct LosslessEncodingOptions 

pub struct LosslessEncodingOptions {
    pub optimization_level: u8,
}

Lossless encoder tuning knobs.

Fields

optimization_level: u8

Compression effort from 0 to 9.

• 0: fastest path, raw-only search
• 1..=3: fast presets that should still beat PNG on typical images
• 4..=6: balanced presets
• 7..=9: increasingly heavy search, with 9 enabling the slowest trials

Trait Implementations

impl Clone for LosslessEncodingOptions

fn clone(&self) -> LosslessEncodingOptions

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for LosslessEncodingOptions

impl Debug for LosslessEncodingOptions

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

Formats the value using the given formatter.

impl Default for LosslessEncodingOptions

fn default() -> Self

Returns the balanced default lossless settings.

impl Eq for LosslessEncodingOptions

impl PartialEq for LosslessEncodingOptions

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