indexmap::map::raw_entry_v1

Struct RawEntryBuilderMut

Source 
pub struct RawEntryBuilderMut<'a, K, V, S> { /* private fields */ }
Expand description

A builder for computing where in an IndexMap a key-value pair would be stored.

This struct is created by the IndexMap::raw_entry_mut_v1 method, provided by the RawEntryApiV1 trait. See its documentation for more.
