Enum CompressionLevel 

pub enum CompressionLevel {
    None,
    Minimal,
    Balanced,
    Aggressive,
    Extreme,
    Focused,
    Semantic,
}

Compression level for output

Variants

None

No compression

Minimal

Remove empty lines, trim whitespace

Balanced

Remove comments, normalize whitespace

Aggressive

Remove docstrings, keep signatures only

Extreme

Key symbols only

Focused

Focused: key symbols with small surrounding context

Semantic

Semantic compression using code understanding

Uses chunk-based compression that:

• Splits content at semantic boundaries (paragraphs, functions)
• Applies budget-ratio-based selection
• When embeddings feature is enabled: clusters similar code and keeps representatives
• When disabled: uses heuristic-based sampling

This provides intelligent compression that preserves code structure better than character-based approaches, though it’s not as sophisticated as full neural semantic analysis.

Expected reduction: ~60-70% (may vary based on content structure)

Implementations

impl CompressionLevel

pub fn expected_reduction(&self) -> u8

Expected reduction percentage

Note: These are approximate values. Actual reduction depends on:

• Content structure (more repetitive = higher reduction)
• Code density (comments/whitespace ratio)
• For Semantic: whether embeddings feature is enabled

pub fn description(&self) -> &'static str

Get a human-readable description of this compression level

pub fn from_str(s: &str) -> Option<Self>

Parse compression level from string

Accepts: “none”, “minimal”, “balanced”, “aggressive”, “extreme”, “semantic” Case-insensitive. Returns None for unrecognized values.

pub fn name(&self) -> &'static str

Get string name of this compression level

pub fn all() -> &'static [Self]

Get all available compression levels

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 Default for CompressionLevel

fn default() -> CompressionLevel

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for CompressionLevel

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl FromStr for CompressionLevel

type Err = ()

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

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.

impl Serialize for CompressionLevel

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for CompressionLevel

impl Eq for CompressionLevel

impl StructuralPartialEq for CompressionLevel
