Expand description

An extension trait for Rows that provides a variety of convenient adapters.

Provided Methods§

Source

fn chain<R: Row>(self, other: R) -> Chain<Self, R>
where Self: Sized,

Adapter for chaining two rows together.

Source

fn project(self, indices: &[usize]) -> Project<'_, Self>
where Self: Sized,

Adapter for projecting a row onto a subset of its columns with the given indices.

§Panics

Panics if indices contains an out-of-bounds index.

Source

fn slice(self, range: impl RangeBounds<usize>) -> Slice<Self>
where Self: Sized,

Adapter for slicing a row with the given range.

§Panics

Panics if range is out of bounds.

Source

fn display(&self) -> impl Display + '_

Source

fn is_null_at(&self, index: usize) -> bool

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
