Struct scrapmetal::MutateEverything

pub struct MutateEverything<M, R, F> where
    M: GenericMutate<R>,
    F: FnMut(R, R) -> R,  { /* fields omitted */ }

Recursively perform a query in a top-down, left-to-right manner across a data structure. The M: GenericMutate<R> queries individual values, while the F: FnMut(R, R) -> R joins the results of multiple queries into a single result.

Methods

impl<M, R, F> MutateEverything<M, R, F> where
    M: GenericMutate<R>,

fn with_query(m: M, fold: F) -> MutateEverything<M, R, F>

Construct a new MutateEverything query traversal.
