# [−][src]Trait nalgebra::base::constraint::SameNumberOfRows

    pub trait SameNumberOfRows<D1: Dim, D2: Dim>: DimEq<D1, D2> + DimEq<D2, D1> {
        type Representative: Dim;
    }

Constraints `D1` and `D2` to be equivalent. They are both assumed to be the number of rows of a matrix.

## Associated Types

### `type Representative: Dim`

This is either equal to `D1` or `D2`, always choosing the one (if any) which is a type-level constant.

## Search Tricks

Prefix searches with a type followed by a colon (e.g., `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g., `vec -> usize` or `* -> vec`)

Search multiple things at once by splitting your query with comma (e.g., `str,u8` or `String,struct:Vec,test`)
