Methods

Name Description
AsBytes<T>(ReadOnlySpan<T>)

Casts a ReadOnlySpan<T> of one primitive type, T, to a ReadOnlySpan<Byte>.
AsBytes<T>(Span<T>)

Casts a Span<T> of one primitive type, T, to a Span<Byte>.
AsMemory<T>(ReadOnlyMemory<T>)

Creates a Memory<T> instance from a ReadOnlyMemory<T>.
AsRef<T>(ReadOnlySpan<Byte>)

Reinterprets a read-only span of bytes as a read-only reference to the structure of type T.
AsRef<T>(Span<Byte>)

Reinterprets a span of bytes as a reference to the structure of type T.
Cast<TFrom,TTo>(ReadOnlySpan<TFrom>)

Casts a read-only span of one primitive type to a read-only span of another primitive type.
Cast<TFrom,TTo>(Span<TFrom>)

Casts a span of one primitive type to a span of another primitive type.
CreateFromPinnedArray<T>(T[], Int32, Int32)

Creates a new memory buffer over the portion of the pre-pinned target array beginning at the start index and consisting of length items.
CreateReadOnlySpan<T>(T, Int32)

Creates a new read-only span over a portion of a regular managed object.
CreateReadOnlySpanFromNullTerminated(Byte*)

Creates a new read-only span for a null-terminated sequence of bytes.
CreateReadOnlySpanFromNullTerminated(Char*)

Creates a new read-only span for a null-terminated string.
CreateSpan<T>(T, Int32)

Creates a new span over a portion of a regular managed object.
GetArrayDataReference(Array)

Returns a reference to the 0th element of array. If the array is empty, returns a reference to where the 0th element would have been stored. Such a reference may be used for pinning but must never be dereferenced.
GetArrayDataReference<T>(T[])

Returns a reference to the 0th element of array. If the array is empty, returns a reference to where the 0th element would have been stored. Such a reference may be used for pinning but must never be dereferenced.
GetReference<T>(ReadOnlySpan<T>)

Returns a reference to the element of the read-only span at index 0.
GetReference<T>(Span<T>)

Returns a reference to the element of the span at index 0.
Read<T>(ReadOnlySpan<Byte>)

Reads a structure of type T out of a read-only span of bytes.
ToEnumerable<T>(ReadOnlyMemory<T>)

Creates an IEnumerable<T> view of the given read-only memory buffer.
TryGetArray<T>(ReadOnlyMemory<T>, ArraySegment<T>)

Tries to get an array segment from the underlying memory buffer. The return value indicates the success of the operation.
TryGetMemoryManager<T,TManager>(ReadOnlyMemory<T>, TManager, Int32, Int32)

Tries to retrieve a MemoryManager<T>, start index, and length from the underlying read-only memory buffer.
TryGetMemoryManager<T,TManager>(ReadOnlyMemory<T>, TManager)

Tries to retrieve a MemoryManager<T> from the underlying read-only memory buffer.
TryGetString(ReadOnlyMemory<Char>, String, Int32, Int32)

Tries to get the underlying string from a System.ReadOnlyMemory<Char>.
TryRead<T>(ReadOnlySpan<Byte>, T)

Tries to read a structure of type T from a read-only span of bytes.
TryWrite<T>(Span<Byte>, T)

Tries to write a structure of type T into a span of bytes.
Write<T>(Span<Byte>, T)

Writes a structure of type T into a span of bytes.
