Struct Explanation 

pub struct Explanation {
    pub original: String,
    pub rewritten: String,
    pub steps: Vec<ExplainStep>,
}

A human-inspectable account of what crate::Ddx::rewrite_sql would do to a statement, produced by crate::Ddx::explain — so a user can see the derivative SQL before running anything. Inspect the fields directly, or print the whole thing (Display) for a readable summary.

Fields

original: String

The original statement, unchanged.

rewritten: String

The statement after every grad/jvp marker is rewritten to derivative SQL — exactly what crate::Ddx::rewrite_sql returns.

steps: Vec<ExplainStep>

One entry per top-level marker, in source order. Empty when the statement has no marker, or in the rare empty-span reprint fallback (where the rewrite still appears in Explanation::rewritten).
