Struct DataRowBuilder 

pub struct DataRowBuilder { /* private fields */ }

Fluent builder for DataRow.

Use DataRowBuilder when you have row-shaped data in memory and want to construct rows incrementally before calling DataRow::into_events or [build_data].

Example

use pharmsol::data::parser::DataRow;
use pharmsol::data::Censor;

let row = DataRow::builder("patient_001", 1.5)
    .evid(0)
    .out(25.5)
    .outeq("cp")
    .cens(Censor::None)
    .covariate("weight", 70.0)
    .covariate("age", 45.0)
    .build();

Implementations

impl DataRowBuilder

pub fn new(id: impl Into<String>, time: f64) -> DataRowBuilder

Create a new builder with required fields

Arguments

• id - Subject identifier
• time - Event time

pub fn evid(self, evid: i32) -> DataRowBuilder

Set the event type

Arguments

• evid - Event ID: 0=observation, 1=dose, 4=reset/new occasion

pub fn dose(self, dose: f64) -> DataRowBuilder

Set the dose amount

Required for EVID=1 (dosing events).

pub fn dur(self, dur: f64) -> DataRowBuilder

Set the infusion duration

If > 0, the dose is treated as an infusion rather than a bolus.

pub fn addl(self, addl: i64) -> DataRowBuilder

Set the additional doses count

Arguments

• addl - Number of additional doses
  • Positive: doses placed after the base time
  • Negative: doses placed before the base time

pub fn ii(self, ii: f64) -> DataRowBuilder

Set the interdose interval

Used with ADDL to specify time between additional doses.

pub fn input(self, input: impl ToString) -> DataRowBuilder

Set the input route label.

Required for EVID=1 dosing rows. The provided value is preserved as the public label until downstream model resolution.

pub fn out(self, out: f64) -> DataRowBuilder

Set the observed value

Used for EVID=0 (observation events).

pub fn outeq(self, outeq: impl ToString) -> DataRowBuilder

Set the output label.

Required for EVID=0 observation rows. The provided value is preserved as the public label until downstream model resolution.

pub fn cens(self, cens: Censor) -> DataRowBuilder

Set the censoring type

pub fn error_poly(self, c0: f64, c1: f64, c2: f64, c3: f64) -> DataRowBuilder

Set error polynomial coefficients

The error polynomial models observation error as: SD = c0 + c1Y + c2Y² + c3*Y³

pub fn covariate(self, name: impl Into<String>, value: f64) -> DataRowBuilder

Add a covariate value

Can be called multiple times to add multiple covariates.

Arguments

• name - Covariate name
• value - Covariate value at this time point

pub fn build(self) -> DataRow

Build the DataRow

Trait Implementations

impl Clone for DataRowBuilder

fn clone(&self) -> DataRowBuilder

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DataRowBuilder

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

Formats the value using the given formatter.
