Defines the swapping strategy for algorithms that need to swap elements in a range (such as partition and sort). The strategy concerns the swapping of elements that are not the core concern of the algorithm. For example, consider an algorithm that sorts [ "abc", "b", "aBc" ] according to toUpper(a) < toUpper(b). That algorithm might choose to swap the two equivalent strings "abc" and "aBc". That does not affect the sorting since both ["abc", "aBc", "b" ] and [ "aBc", "abc", "b" ] are valid outcomes.
bringToFront takes two ranges front and back, which may be of different types. Considering the concatenation of front and back one unified range, bringToFront rotates that unified range such that all elements in back are brought to the beginning of the unified range. The relative ordering of elements in front and back, respectively, remains unchanged.
Copies the content of source into target and returns the remaining (unfilled) part of target.
Assigns value to each element of input range range.
Initializes all elements of range with their .init value. Assumes that the elements of the range are uninitialized.
Moves source into target, via a destructive copy when necessary.
Calls move(a, b) for each element a in src and the corresponding element b in tgt, in increasing order.
Similar to move but assumes target is uninitialized. This is more efficient because source can be blitted over target without destroying or initializing it first.
Similar to moveAll but assumes all elements in tgt are uninitialized. Uses moveEmplace to move elements from src over elements from tgt.
Same as moveSome but assumes all elements in tgt are uninitialized. Uses moveEmplace to move elements from src over elements from tgt.
Calls move(a, b) for each element a in src and the corresponding element b in tgt, in increasing order, stopping when either range has been exhausted.
Eliminates elements at given offsets from range and returns the shortened range.
Reduces the length of the bidirectional range range by removing elements that satisfy pred. If s = SwapStrategy.unstable, elements are moved from the right end of the range over the elements to eliminate. If s = SwapStrategy.stable (the default), elements are moved progressively to front such that their relative order is preserved. Returns the filtered range.
Reverses r in-place. Performs r.length / 2 evaluations of swap. UTF sequences consisting of multiple code units are preserved properly.
The strip group of functions allow stripping of either leading, trailing, or both leading and trailing elements.
Swaps lhs and rhs. The instances lhs and rhs are moved in memory, without ever calling opAssign, nor any other function. T need not be assignable at all to be swapped.
Swaps two elements in-place of a range r, specified by their indices i1 and i2.
Swaps all elements of r1 with successive elements in r2. Returns a tuple containing the remainder portions of r1 and r2 that were not swapped (one of them will be empty). The ranges may be of different types but must have the same element type and support swapping.
Initializes each element of range with value. Assumes that the elements of the range are uninitialized. This is of interest for structs that define copy constructors (for all other types, fill and uninitializedFill are equivalent).
This is a submodule of std.algorithm. It contains generic mutation algorithms.
