An indexer for the raw jagged arrays.

Required Methods

unsafe fn jagged_index_unchecked<'a, T>( &self, arrays: &impl Slices<'a, T>, flat_index: usize, ) -> JaggedIndex

where T: 'a,

Returns the jagged index of the element flat_index-th position if the raw jagged array defined by the arrays collection would have been flattened.

Unlike jagged_index, this method expects flat_index <= arrays.iter().map(|x| x.len()).sum(), and omits bounds checks.

SAFETY

Calling this method with an index greater than the total length of the jagged array might possibly lead to undefined behavior.

unsafe fn jagged_index_unchecked_from_slice<'a, T>( &self, arrays: &[impl AsRawSlice<T>], flat_index: usize, ) -> JaggedIndex

where T: 'a,

Returns the jagged index of the element flat_index-th position if the raw jagged array defined by the arrays collection would have been flattened.

Unlike jagged_index, this method expects flat_index <= arrays.iter().map(|x| x.len()).sum(), and omits bounds checks.

SAFETY

Calling this method with an index greater than the total length of the jagged array might possibly lead to undefined behavior.

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.
