NonEmptyMVector is a thin wrapper around MVector that witnesses an API requiring non-empty construction, initialization, and generation of non-empty vectors by design.

A newtype wrapper was chosen so that no new pointer indirection is introduced when working with MVectors, and all performance characteristics inherited from the MVector API still apply.

Length of the mutable vector.

Yield a part of the mutable vector without copying.

Yield all but the last element without copying.

Yield all but the first element without copying.

Yield at the first n elements without copying.

Yield all but the first n elements without copying.

Yield the first n elements paired with the remainder without copying.

Yield a part of the mutable vector without copying it. No bounds checks are performed.

Yield the first n elements without copying. The vector must contain at least n elements but this is not checked.

Yield all but the first n elements without copying. The vector must contain at least n elements but this is not checked.

Check whether two vectors overlap.

Convert a mutable vector to a non-empty mutable vector

Convert a non-empty mutable vector to a mutable vector

Convert a mutable vector to a non-empty mutable vector

Warning: this function is unsafe and can result in empty non-empty mutable vectors. If you call this function, the onus is on you to make sure the mutable vector being converted is not empty.

Create a mutable vector of the given length.

Create a mutable vector of the given length which is max n 1.

Create a mutable vector of the given length. The memory is not initialized.

Create a mutable vector of the given length (0 if the length is negative) and fill it with an initial value.

Create a mutable vector of the length max n 1 for a given length, and fill it with an initial value.

Create a mutable vector of the given length (0 if the length is negative) and fill it with values produced by repeatedly executing the monadic action.

Create a mutable vector of the length max n 1 for a given length, and fill it with values produced by repeatedly executing the monadic action.

Create a copy of a mutable vector.

Grow a vector by the given number of elements. The number must be positive.

Grow a vector by the given number of elements. The number must be positive but this is not checked.

Reset all elements of the vector to some undefined value, clearing all references to external objects. This is usually a noop for unboxed vectors.

Yield the element at the given position.

Replace the element at the given position.

Modify the element at the given position.

Swap the elements at the given positions.

Yield the element at the given position. No bounds checks are performed.

Replace the element at the given position. No bounds checks are performed.

Modify the element at the given position. No bounds checks are performed.

Swap the elements at the given positions. No bounds checks are performed.

Compute the next (lexicographically) permutation of given vector in-place. Returns False when input is the last permtuation

Set all elements of the vector to the given value.

Copy a vector. The two vectors must have the same length and may not overlap.

Move the contents of a vector. The two vectors must have the same length.

If the vectors do not overlap, then this is equivalent to copy. Otherwise, the copying is performed as if the source vector were copied to a temporary vector and then the temporary vector was copied to the target vector.

Copy a vector. The two vectors must have the same length and may not overlap. This is not checked.

Move the contents of a vector. The two vectors must have the same length, but this is not checked.

If the vectors do not overlap, then this is equivalent to unsafeCopy. Otherwise, the copying is performed as if the source vector were copied to a temporary vector and then the temporary vector was copied to the target vector.
