Sundew.Base.Equality 11.0.0-u20231120-225113-ci

Sundew.Base

Sundew.Base is a collection of smaller NuGet packages that work on various .NETStandard targets:

Collections

Contains various Linq style extension methods for collection types suchs IEnumerable, IReadOnlyList etc.

• For, ForEach, ForReverse, IndexOf, ToReadOnly.
• AllOrFailed extension allows seemless conversion from IEnumerable<TItem?> to IEnumerable<TItem>.
• ByCardinality extension allows checking whether an IEnumerable<TItem> is empty, has a single element or multiple elements.
• Value-Array, List and Dictionary* wrappers for Immutable collections with value semantics. (* Not on NETStandard1.2)

Disposal

• DisposeAction for wrapping an Action in an IDisposable.
• Disposer provides disposal of a fixed set of IDisposables.
• DisposableState provides an easy way to implement the Dispose(bool) pattern.
• DisposingDictionary allows building a list of IDisposables that supports disposal by a key and otherwise supports disposal in the same order.
• DisposingList allows building a list of IDisposables for disposal in the same order.

IAsyncDisposable is only supported on .NETStandard2.1

Equality

• ReferenceEqualityComparer compares objects by reference.
• TargetEqualityWeakReference is a weak reference that implements equality based on target equality.

Initialization

• IInitializable for implementing async initialization logic.
• InitializeAction for wrapping an Action in an IInitializable.
• Initializer provides initialization of IInitializables.
• InitializeFlag for keeping tracking whether initialization is completed.

Memory

• Buffer allows building arrays
• Split extensions allows Linq style splitting memory in to segments.

Primitives

• Interval represents an interval of two values.
• Percentage as a value type.
• DateTime provider.
• Result type (R) and Option type (O).
• Attempter for implementing retry logic.

Text

• AlignedString and AlignAndLimitFormatProvider providers aligning and length limiting string formatting.
• NamedFormatString allows to define a string format using names rather than indices.
• NaturalTextComparer does logical text comparison for all platforms with performance similar to the Windows specific StrCmpLogicalW.
• AppendItems allows joining items into a StringBuilder.

Threading and Threading.Jobs

• AsyncLazy provides a cancellable async lazy implementation
• AsyncLock provides async locking.
• Flag is an Interlocked.Exchanged based flag.
• CancellableJob is implementation of a cancellable task.
• ContinusJob is implementation of a cancellable task that keeps running.

Timers

• Timer is an easy to use and modify timer.
