Module typed_dataframe 

Parser and expansion for the typed_dataframe! macro.

Generates a struct that wraps an R data.frame, validates declared columns via TryFromSexp, and exposes borrowed per-column accessors.

Syntax

typed_dataframe! {
    /// The shape we accept for the Theoph PK dataset.
    pub TheophDf {
        subject: i32,
        weight: f64,
        dose: f64,
        flag: Option<i32>,   // optional column
    }
}

Expands to a struct TheophDf with TryFromSexp and per-column accessors (subject() -> &[i32], flag() -> Option<&[i32]>).
