Struct SupportJacobian 

pub struct SupportJacobian {
    pub starts: Vec<usize>,
    pub offsets: Vec<usize>,
    pub values: Vec<f64>,
    pub parameter_count: usize,
}

Per-peak Jacobian stored only over each peak’s active support.

Fields

starts: Vec<usize>

First active grid index for each peak.

offsets: Vec<usize>

Prefix sum of active sample counts, with length peak_count + 1.

values: Vec<f64>

Sample-major derivative rows with parameter_count values per sample.

parameter_count: usize

Number of local derivative columns per active sample.

Implementations

impl SupportJacobian

pub fn peak_count(&self) -> usize

Number of represented peaks.

pub fn active_sample_count(&self) -> usize

Total number of active peak/sample pairs.

pub fn to_dense(&self, sample_count: usize) -> Result<Vec<f64>, ProfileError>

Materialize a parameter-major dense (peak, parameter, sample) Jacobian.

Errors

Returns ProfileError if the dense allocation size overflows or the supplied sample count is inconsistent with a stored support block.
