Ways digit span6/13/2023 ![]() Buffer in the pseudo-code represents a Memory or Span buffer of type Char. The following pseudo-code example illustrates these three concepts. The lease is the length of time that a particular component is allowed to be the consumer of the buffer. The active consumer of a buffer isn't necessarily the buffer's owner. Buffers can have one consumer at a time unless some external synchronization mechanism is provided. The consumer of a buffer instance is allowed to use the buffer instance by reading from it and possibly writing to it. Ownership can also be transferred Component-A can relinquish control of the buffer to Component-B, at which point Component-A may no longer use the buffer, and Component-B becomes responsible for destroying the buffer when it's no longer in use.Ĭonsumption. Generally the owner is the component that created the buffer or that received the buffer from a factory. The owner of a buffer instance is responsible for lifetime management, including destroying the buffer when it's no longer in use. Owners, consumers, and lifetime managementīuffers can be passed around between APIs and can sometimes be accessed from multiple threads, so be aware of how a buffer's lifetime is managed. Because Memory and its related types can be accessed by multiple components or by multiple threads, it's important to follow some standard usage guidelines to produce robust code. That is, they're designed so that some or all of the data can be efficiently passed to components in the pipeline, which can process them and optionally modify the buffer. Unlike Span, Memory can be stored on the managed heap.īoth Span and Memory are wrappers over buffers of structured data that can be used in pipelines. Like Span, Memory and its related types can be backed by both managed and unmanaged memory. NET 2.1 added some additional types, including Memory, ReadOnlyMemory, IMemoryOwner, and MemoryPool. Because these types can only be stored on the stack, they're unsuitable for scenarios such as asynchronous method calls. Span and ReadOnlySpan are lightweight memory buffers that wrap references to managed or unmanaged memory. NET includes a number of types that represent an arbitrary contiguous region of memory.
