Enum QuantMode 

#[non_exhaustive]
pub enum QuantMode {
    Bits8,
    Bits3_5,
    Bits2_5,
}

Available on crate feature alloc only.

Quantization bit depth. Controls the quality/compression tradeoff.

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.

Bits8

8-bit: 256 levels, 4 values per u32. Near-lossless (~0.4% max error). ~8x compression vs f64. Simple byte packing.

Bits3_5

3.5-bit: 11 levels, 7 values per u32. Aggressive (~10% max error). ~14x compression vs f64. Base-11 mixed-radix packing.

Bits2_5

2.5-bit: 5 levels, 13 values per u32. Ultra-aggressive (~20% max error). ~21x compression vs f64. Base-5 mixed-radix packing.

Trait Implementations

impl Clone for QuantMode

fn clone(&self) -> QuantMode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for QuantMode

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

Formats the value using the given formatter.

impl PartialEq for QuantMode

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