Enum CompressionLevel 

pub enum CompressionLevel {
    Fastest,
    Fast,
    Balanced,
    Best,
    Custom(u32),
}

Compression level settings that balance processing speed vs. compression ratio

This enum provides predefined compression levels optimized for different use cases, allowing users to choose the appropriate trade-off between compression speed and the resulting compression ratio.

Level Characteristics

• Fastest: Minimal compression for maximum speed (level 1-2)
• Fast: Light compression with good speed (level 3-4)
• Balanced: Optimal balance of speed and compression (level 5-6)
• Best: Maximum compression ratio, slower processing (level 9-11)
• Custom: User-defined level for fine-tuned control

Performance Impact

Higher compression levels generally result in:

• Better compression ratios (smaller output)
• Increased processing time
• Higher memory usage
• More CPU utilization

Examples

Variants

Fastest

Fastest compression with minimal ratio optimization Suitable for real-time processing and streaming applications

Fast

Fast compression with light optimization Good for interactive applications requiring quick response

Balanced

Balanced compression optimizing both speed and ratio Recommended for most general-purpose applications

Best

Best compression ratio with slower processing Ideal for archival storage and bandwidth-limited scenarios

Custom(u32)

Custom compression level for fine-tuned control Value interpretation depends on the specific algorithm

Implementations

impl CompressionLevel

pub fn to_numeric(&self, algorithm: &CompressionAlgorithm) -> u32

Gets the numeric level for the compression algorithm

Trait Implementations

impl Clone for CompressionLevel

fn clone(&self) -> CompressionLevel

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CompressionLevel

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

Formats the value using the given formatter.

impl Display for CompressionLevel

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

Formats the value using the given formatter.

impl PartialEq for CompressionLevel

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