Struct TraceStoragePolicy 

pub struct TraceStoragePolicy {
    pub compression: CompressionAlgorithm,
    pub retention_days: u32,
    pub max_size_bytes: u64,
    pub sample_rate: f64,
}

Trace storage configuration policy

Controls how experiment traces are stored, compressed, and retained.

Fields

compression: CompressionAlgorithm

Compression algorithm to use for trace data

retention_days: u32

Number of days to retain trace data (0 = indefinite)

max_size_bytes: u64

Maximum storage size in bytes (0 = unlimited)

sample_rate: f64

Sampling rate for trace collection (0.0-1.0) 1.0 = collect all traces, 0.5 = collect 50%, etc.

Implementations

impl TraceStoragePolicy

pub fn new( compression: CompressionAlgorithm, retention_days: u32, max_size_bytes: u64, sample_rate: f64, ) -> Self

Create a new trace storage policy

pub fn minimal() -> Self

Create a minimal policy (no compression, short retention)

pub fn development() -> Self

Create a policy optimized for development (high detail, short retention)

pub fn production() -> Self

Create a policy optimized for production (balanced)

pub fn archival() -> Self

Create a policy for archival (high compression, long retention)

pub fn should_sample(&self, trace_id: &str) -> bool

Check if a trace should be sampled based on the sample rate

Uses a deterministic hash of the trace ID for consistent sampling.

pub fn estimate_compressed_size(&self, uncompressed_bytes: u64) -> u64

Estimate the compressed size of data given uncompressed size

pub fn would_exceed_limit( &self, current_bytes: u64, additional_bytes: u64, ) -> bool

Check if adding data would exceed the storage limit

pub fn is_indefinite_retention(&self) -> bool

Check if retention is indefinite

pub fn is_unlimited_storage(&self) -> bool

Check if storage is unlimited

pub fn sample_percentage(&self) -> f64

Get the effective sample percentage (0-100)

pub fn validate(&self) -> Result<(), PolicyValidationError>

Validate the policy configuration

Trait Implementations

impl Clone for TraceStoragePolicy

fn clone(&self) -> TraceStoragePolicy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TraceStoragePolicy

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

Formats the value using the given formatter.

impl Default for TraceStoragePolicy

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for TraceStoragePolicy

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for TraceStoragePolicy

fn eq(&self, other: &TraceStoragePolicy) -> 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 TraceStoragePolicy

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
