Struct EvalSession 

pub struct EvalSession { /* private fields */ }

Evaluation session for codec comparison.

Example

use codec_eval::{EvalSession, EvalConfig, ViewingCondition, ImageData};

let config = EvalConfig::builder()
    .report_dir("./reports")
    .viewing(ViewingCondition::desktop())
    .build();

let mut session = EvalSession::new(config);

session.add_codec("my-codec", "1.0.0", Box::new(|image, request| {
    // Encode the image
    Ok(encoded_bytes)
}));

let report = session.evaluate_image("test.png", image_data)?;

Implementations

impl EvalSession

pub fn new(config: EvalConfig) -> Self

Create a new evaluation session.

pub fn add_codec( &mut self, id: &str, version: &str, encode: EncodeFn, ) -> &mut Self

Register a codec with an encode callback.

pub fn add_codec_with_decode( &mut self, id: &str, version: &str, encode: EncodeFn, decode: DecodeFn, ) -> &mut Self

Register a codec with both encode and decode callbacks.

pub fn codec_count(&self) -> usize

Get the number of registered codecs.

pub fn evaluate_image( &self, name: &str, image: ImageData, ) -> Result<ImageReport>

Evaluate a single image across all registered codecs.

Arguments

• name - Image name or identifier.
• image - The image data to evaluate.

Returns

An ImageReport containing results for all codec/quality combinations.

pub fn write_image_report(&self, report: &ImageReport) -> Result<()>

Write an image report to the configured report directory.

pub fn write_corpus_report(&self, report: &CorpusReport) -> Result<()>

Write a corpus report to the configured report directory.
