Struct RdCurve 

pub struct RdCurve {
    pub label: String,
    pub metric: QualityMetric,
    /* private fields */
}

An RD curve consisting of multiple measurement points.

Fields

label: String

Label for this curve (e.g. codec name, preset).

metric: QualityMetric

Quality metric used.

Implementations

impl RdCurve

pub fn new(label: impl Into<String>, metric: QualityMetric) -> Self

Create a new empty RD curve.

pub fn add_point(&mut self, point: RdPoint)

Add a measurement point and maintain sorted order.

pub fn point_count(&self) -> usize

Return the number of points.

pub fn points(&self) -> &[RdPoint]

Return all points as a slice.

pub fn best_quality(&self) -> Option<&RdPoint>

Find the point with the highest quality.

pub fn lowest_bitrate(&self) -> Option<&RdPoint>

Find the point with the lowest bitrate.

pub fn find_nearest_quality(&self, target: f64) -> Option<&RdPoint>

Find the operating point closest to a target quality.

pub fn find_nearest_bitrate(&self, target_kbps: f64) -> Option<&RdPoint>

Find the operating point closest to a target bitrate.

pub fn interpolate_quality(&self, bitrate_kbps: f64) -> Option<f64>

Linearly interpolate quality at a given bitrate. Returns None if outside the curve range or fewer than 2 points.
