Trait DataSelector 

pub trait DataSelector {
    // Required method
    fn resolve_indices(&self, count: usize) -> Vec<usize>;

    // Provided method
    fn is_contiguous(&self) -> bool { ... }
}

Trait for types that can specify a data selection (index-based dimension)

Required Methods

fn resolve_indices(&self, count: usize) -> Vec<usize>

Resolve this selection to indices (within the given count)

Provided Methods

fn is_contiguous(&self) -> bool

Returns true if this selector represents a contiguous range. Range types (Range, RangeFrom, etc.) return true. Index arrays (&usize, Vec) return false.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
