The for adding services. A delegate to configure the . Provides support for efficiently using Tasks to implement the APM (Begin/End) pattern. Marshals the Task as an IAsyncResult, using the supplied callback and state to implement the APM pattern. The Task to be marshaled. The callback to be invoked upon completion. The state to be stored in the IAsyncResult. An IAsyncResult to represent the task's asynchronous operation. Processes an IAsyncResult returned by Begin. The IAsyncResult to unwrap. Processes an IAsyncResult returned by Begin. The IAsyncResult to unwrap. Provides a simple IAsyncResult that wraps a Task. We could use the Task as the IAsyncResult if the Task's AsyncState is the same as the object state, but that's very rare, in particular in a situation where someone cares about allocation, and always using TaskAsyncResult simplifies things and enables additional optimizations. The wrapped Task. Callback to invoke when the wrapped task completes. Initializes the IAsyncResult with the Task to wrap and the associated object state. The Task to wrap. The new AsyncState value. Callback to invoke when the wrapped task completes. Invokes the callback. Gets a user-defined object that qualifies or contains information about an asynchronous operation. Gets a value that indicates whether the asynchronous operation completed synchronously. This is set lazily based on whether the has completed by the time this object is created. Gets a value that indicates whether the asynchronous operation has completed. Gets a that is used to wait for an asynchronous operation to complete. The End represents the offset into AvailableMemory where the range of "active" bytes ends. At the point when the block is leased the End is guaranteed to be equal to Start. The value of Start may be assigned anywhere between 0 and Buffer.Length, and must be equal to or less than End. Reference to the next block of data when the overall "active" bytes spans multiple blocks. At the point when the block is leased Next is guaranteed to be null. Start, End, and Next are used together in order to create a linked-list of discontiguous working memory. The "active" memory is grown when bytes are copied in, End is increased, and Next is assigned. The "active" memory is shrunk when bytes are consumed, Start is increased, and blocks are returned to the pool. A simple struct we wrap reference types inside when storing in arrays to bypass the CLR's covariant checks when writing to arrays. We use as a wrapper to avoid paying the cost of covariant checks whenever the underlying array that the class uses is written to. We've recognized this as a perf win in ETL traces for these stack frames: clr!JIT_Stelem_Ref clr!ArrayStoreCheck clr!ObjIsInstanceOf Get a pinnable reference to the builder. Does not ensure there is a null char after This overload is pattern matched in the C# 7.3+ compiler so you can omit the explicit method call, and write eg "fixed (char* c = builder)" Get a pinnable reference to the builder. Ensures that the builder has a null char after Returns the underlying storage of the builder. Returns a span around the contents of the builder. Ensures that the builder has a null char after Resize the internal buffer either by doubling current buffer size or by adding to whichever is greater. Number of chars requested beyond current position.
