Struct EcsReport 

pub struct EcsReport {

    pub spec_version: String,
    pub codec: String,
    pub dataset: String,
    pub n_files: usize,
    pub bit_exact: bool,
    pub grade: char,
    pub cr: f64,
    pub prd: f64,
    pub prdn: f64,
    pub r: f64,
    pub snr_db: f64,
    pub qs: f64,
    pub per_band: Vec<BandResult>,
    pub throughput_mibs: f64,
    pub peak_bytes: u64,
    pub violations: Vec<String>,
}

The standard OpenECS report for one codec evaluated on one dataset.

This is the canonical, self-describing record the standard produces: every field a third party needs to reproduce, audit, or compare the claim is present. It serializes to stable JSON (the exchange format) via EcsReport::to_json and renders a human-aligned summary via EcsReport::human_table. The cross-codec comparison output is leaderboard.

Field groups:

• identity: codec, dataset, n_files
• verdict: bit_exact, grade
• aggregate fidelity: cr, prd, prdn, r, snr_db, qs
• per-band breakdown: per_band
• resource cost: throughput_mibs, peak_bytes
• audit trail: violations (why the next-higher tier failed)

Fields

spec_version: String

OpenECS spec version this report conforms to (e.g. “1.0”), so a report is self-identifying out of context. Stamped by the harness.

codec: String

Codec name, e.g. “lamquant-lossless” or “gzip”.

dataset: String

Dataset / holdout corpus identifier, e.g. “tuh-eeg-holdout”.

n_files: usize

Number of files in the run.

bit_exact: bool

True iff reconstruction was bit-exact on the integer sample domain.

grade: char

OpenECS tier code: ‘L’, ‘C’, ‘M’, ‘A’, or ‘\0’ for below-floor.

cr: f64

Aggregate (pooled) compression ratio (raw / compressed).

prd: f64

Aggregate PRD in percent.

prdn: f64

Aggregate normalized (mean-subtracted) PRD in percent.

r: f64

Aggregate Pearson correlation R.

snr_db: f64

Aggregate SNR in dB.

qs: f64

Quality score CR / PRD (raw CR when lossless). Higher is better.

per_band: Vec<BandResult>

Per-band fidelity breakdown, in canonical band order.

throughput_mibs: f64

Encode+decode throughput in MiB/s.

peak_bytes: u64

Peak resident memory during the run, in bytes.

violations: Vec<String>

Why the next-higher tier failed — the climb-a-tier to-do list.

Implementations

impl EcsReport

pub fn grade_str(&self) -> String

The grade as a display string, or “” for the below-floor sentinel.

pub fn passed(&self) -> bool

True iff the codec reached any compliant tier (grade != ‘\0’).

pub fn to_json(&self) -> String

Serialize this report to pretty JSON — the standard exchange format.

Serialization of this plain-data struct cannot fail in practice; the expect guards a genuinely unreachable serde error.

pub fn from_json(s: &str) -> Result<Self, Error>

Parse an EcsReport back from its JSON form.

pub fn human_table(&self) -> String

Render an aligned, human-readable text summary of this report.

Two blocks: a header with identity + verdict + aggregate metrics, then a fixed-width per-band table. Memory is shown in MiB for readability. The exact byte / float values stay in the JSON form.

Trait Implementations

impl Clone for EcsReport

fn clone(&self) -> EcsReport

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EcsReport

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for EcsReport

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for EcsReport

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
