# shrinkage::WorkingSetPolicy Shrinkage for Rust · 0.3.0 [Source]() ```rust pub enum WorkingSetPolicy ``` Feature selection for restricted numerical updates. Every policy retains current nonzeros. Excluded zeros can reenter after a complete optimality check; only the original problem certifies convergence. ## Variants ### `Adaptive` ```rust Adaptive { initial_size: usize, prune: bool } ``` [Source]() Rank features by optimality violation, always retaining current nonzeros. #### `initial_size` ```rust initial_size: usize ``` [Source]() Positive initial feature budget, enlarged to retain the starting support. #### `prune` ```rust prune: bool ``` [Source]() Rebuild around twice the support instead of retaining and doubling the set. ### `Auto` ```rust Auto ``` [Source]() Adaptive sets for single fits, and ever-active sets for paths. ### `Disabled` ```rust Disabled ``` [Source]() Update every feature allowed by independently configured screening. ### `EverActive` ```rust EverActive ``` [Source]() Retain features activated at accepted iterates, including earlier path points. ## Inherent implementation [Source]() ```rust impl WorkingSetPolicy ``` ## Implementation of Clone [Source]() ```rust impl Clone for WorkingSetPolicy ``` ### `clone` ```rust fn clone(&self) -> Self ``` [Source]() ## Implementation of Copy [Source]() ```rust impl Copy for WorkingSetPolicy ``` ## Implementation of Debug [Source]() ```rust impl Debug for WorkingSetPolicy ``` ### `fmt` ```rust fn fmt(&self, f: &mut core::fmt::Formatter<'_>) -> core::fmt::Result ``` [Source]() ## Implementation of Default [Source]() ```rust impl Default for WorkingSetPolicy ``` ### `default` ```rust fn default() -> Self ``` [Source]() ## Implementation of Eq [Source]() ```rust impl Eq for WorkingSetPolicy ``` ## Implementation of PartialEq [Source]() ```rust impl PartialEq for WorkingSetPolicy ``` ### `eq` ```rust fn eq(&self, other: &Self) -> bool ``` [Source]() ## Implementation of StructuralPartialEq [Source]() ```rust impl StructuralPartialEq for WorkingSetPolicy ``` ## Implementation of Freeze ```rust impl Freeze for WorkingSetPolicy ``` ## Implementation of RefUnwindSafe ```rust impl RefUnwindSafe for WorkingSetPolicy ``` ## Implementation of Send ```rust impl Send for WorkingSetPolicy ``` ## Implementation of Sync ```rust impl Sync for WorkingSetPolicy ``` ## Implementation of Unpin ```rust impl Unpin for WorkingSetPolicy ``` ## Implementation of UnsafeUnpin ```rust impl UnsafeUnpin for WorkingSetPolicy ``` ## Implementation of UnwindSafe ```rust impl UnwindSafe for WorkingSetPolicy ``` ## Implementation of Any ```rust impl Any for T where T: 'static + ?Sized ``` ## Implementation of Boilerplate ```rust impl Boilerplate for T where T: Copy + Send + Sync + Debug + PartialEq + 'static ``` ## Implementation of Borrow ```rust impl Borrow for T where T: ?Sized ``` ## Implementation of BorrowMut ```rust impl BorrowMut for T where T: ?Sized ``` ## Implementation of ByRef ```rust impl ByRef for T ``` ## Implementation of CastableFrom ```rust impl CastableFrom for DT where ST: ?Sized, DT: ?Sized ``` ## Implementation of CastableFrom ```rust impl CastableFrom for DT where ST: ?Sized, DT: ?Sized ``` ## Implementation of CloneToUninit ```rust impl CloneToUninit for T where T: Clone ``` ## Implementation of Equivalent ```rust impl Equivalent for Q where Q: Eq + ?Sized, K: Borrow + ?Sized ``` ## Implementation of Equivalent ```rust impl Equivalent for Q where Q: Eq + ?Sized, K: Borrow + ?Sized ``` ## Implementation of From ```rust impl From for T ``` ## Implementation of Imply ```rust impl Imply for U where T: ?Sized, U: ?Sized ``` ## Implementation of Into ```rust impl Into for T where U: From ``` ## Implementation of IntoEither ```rust impl IntoEither for T ``` ## Implementation of Pointable ```rust impl Pointable for T ``` ## Implementation of Read ```rust impl Read for T where T: ?Sized ``` ## Implementation of Same ```rust impl Same for T ``` ## Implementation of Scalar ```rust impl Scalar for T where T: 'static + Clone + PartialEq + Debug ``` ## Implementation of SupersetOf ```rust impl SupersetOf for SP where SS: SubsetOf ``` ## Implementation of ToOwned ```rust impl ToOwned for T where T: Clone ``` ## Implementation of TryFrom ```rust impl TryFrom for T where U: Into ``` ## Implementation of TryInto ```rust impl TryInto for T where U: TryFrom ```
