Trait Frame

pub trait Frame {
    // Required methods
    fn ncols(&self) -> usize;
    fn nrows(&self) -> usize;
    fn column(&self, i: usize) -> &NamedColumn;

    // Provided method
    fn columns(&self) -> FrameColIter<'_, Self> { ... }
}

Required Methods

fn ncols(&self) -> usize

fn nrows(&self) -> usize

fn column(&self, i: usize) -> &NamedColumn

Provided Methods

fn columns(&self) -> FrameColIter<'_, Self>

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.
