# shrinkage::CoefficientLayout Shrinkage for Rust · 0.3.0 [Source]() ```rust pub struct CoefficientLayout ``` A feature-by-response coefficient matrix stored in response-major order. Each response owns a contiguous vector of feature coefficients. Entry `(feature, response)` has index `response * nfeatures + feature`. Intercepts are separate and never appear in this layout. This CPU layout is provisional. ## Inherent implementation [Source]() ```rust impl CoefficientLayout ``` ### `index` ```rust pub fn index(self, feature: usize, response: usize) -> Option ``` [Source]() Flat index of a feature and response, or `None` for an invalid axis index. ### `is_empty` ```rust pub fn is_empty(self) -> bool ``` [Source]() Whether there are no feature coefficients. ### `len` ```rust pub fn len(self) -> usize ``` [Source]() Number of coefficient entries, excluding intercepts. ### `new` ```rust pub fn new(nfeatures: usize, nresponses: usize) -> Result ``` [Source]() Specify both axes, allowing zero features but requiring a response. #### Errors Reject zero responses or a coefficient count that overflows `usize`. ### `nfeatures` ```rust pub fn nfeatures(self) -> usize ``` [Source]() Number of training features. ### `nresponses` ```rust pub fn nresponses(self) -> usize ``` [Source]() Number of responses. ## Implementation of Clone [Source]() ```rust impl Clone for CoefficientLayout ``` ### `clone` ```rust fn clone(&self) -> Self ``` [Source]() ## Implementation of Copy [Source]() ```rust impl Copy for CoefficientLayout ``` ## Implementation of Debug [Source]() ```rust impl Debug for CoefficientLayout ``` ### `fmt` ```rust fn fmt(&self, f: &mut core::fmt::Formatter<'_>) -> core::fmt::Result ``` [Source]() ## Implementation of Eq [Source]() ```rust impl Eq for CoefficientLayout ``` ## Implementation of PartialEq [Source]() ```rust impl PartialEq for CoefficientLayout ``` ### `eq` ```rust fn eq(&self, other: &Self) -> bool ``` [Source]() ## Implementation of StructuralPartialEq [Source]() ```rust impl StructuralPartialEq for CoefficientLayout ``` ## Implementation of Freeze ```rust impl Freeze for CoefficientLayout ``` ## Implementation of RefUnwindSafe ```rust impl RefUnwindSafe for CoefficientLayout ``` ## Implementation of Send ```rust impl Send for CoefficientLayout ``` ## Implementation of Sync ```rust impl Sync for CoefficientLayout ``` ## Implementation of Unpin ```rust impl Unpin for CoefficientLayout ``` ## Implementation of UnsafeUnpin ```rust impl UnsafeUnpin for CoefficientLayout ``` ## Implementation of UnwindSafe ```rust impl UnwindSafe for CoefficientLayout ``` ## 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 ```
