Struct CompressionBias 

pub struct CompressionBias {
    pub preserve_tools: bool,
    pub preserve_thinking: bool,
    pub preserve_user_questions: bool,
    pub compact_long_outputs: bool,
    pub aggressive: bool,
    pub preserve_keywords: Vec<String>,
}

Compression bias - controls what to prioritize during compression.

Fields

preserve_tools: bool

Preserve tool calls and their results (important operations).

preserve_thinking: bool

Preserve thinking blocks (reasoning process).

preserve_user_questions: bool

Preserve user questions (even if old).

compact_long_outputs: bool

Compact long outputs instead of removing them.

aggressive: bool

Aggressive mode - remove more content.

preserve_keywords: Vec<String>

Custom keywords to preserve messages containing them.

Implementations

impl CompressionBias

pub fn balanced() -> Self

Default bias - balanced preservation.

pub fn preserve_important() -> Self

Preserve all important content (tools, thinking, decisions).

pub fn aggressive() -> Self

Aggressive compression - remove as much as possible.

pub fn tool_focused() -> Self

Focus on preserving tool operations.

pub fn parse(spec: &str) -> Result<Self>

Parse bias from a string specification. Format: “preserve:tools,thinking,user” or “aggressive” or “balanced”

pub fn format(&self) -> String

Format bias for display.

Trait Implementations

impl Clone for CompressionBias

fn clone(&self) -> CompressionBias

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CompressionBias

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

Formats the value using the given formatter.

impl Default for CompressionBias

fn default() -> CompressionBias

Returns the “default value” for a type.
