ValueType
ReadOnlySequence<T>

Constructors

ReadOnlySequence<T>(ReadOnlyMemory<T>)

Creates an instance of ReadOnlySequence<T> from a ReadOnlyMemory<T>.
ReadOnlySequence<T>(ReadOnlySequenceSegment<T>, Int32, ReadOnlySequenceSegment<T>, Int32)

Creates an instance of a ReadOnlySequence<T> from a linked memory list represented by start and end segments and the corresponding indexes in them.
ReadOnlySequence<T>(T[])

Creates an instance of ReadOnlySequence<T> from the array.
ReadOnlySequence<T>(T[], Int32, Int32)

Creates an instance of a ReadOnlySequence<T> from a section of an array.

Fields

Empty

Returns an empty ReadOnlySequence<T>.

Properties

End

Gets the position at the end of the ReadOnlySequence<T>.
First

Gets the ReadOnlyMemory<T> from the first segment.
FirstSpan

Gets the ReadOnlySpan<T> from the first segment.
IsEmpty

Gets a value that indicates whether the ReadOnlySequence<T> is empty.
IsSingleSegment

Gets a value that indicates whether the ReadOnlySequence<T> contains a single ReadOnlyMemory<T> segment.
Length

Gets the length of the ReadOnlySequence<T>.
Start

Gets the position to the start of the ReadOnlySequence<T>.

Methods

GetEnumerator()

Returns an enumerator over the ReadOnlySequence<T>.
GetPosition(Int64)

Returns a new SequencePosition at an offset from the start of the sequence.
GetPosition(Int64, SequencePosition)

Returns a new SequencePosition starting at the specified offset from the origin position.
Slice(Int32, Int32)

Forms a slice out of the current ReadOnlySequence<T>, beginning at start, with length items.
Slice(Int32, SequencePosition)

Forms a slice out of the current ReadOnlySequence<T>, beginning at start and ending at end (exclusive).
Slice(Int64)

Forms a slice out of the current ReadOnlySequence<T>, beginning at a specified index and continuing to the end of the read-only sequence.
Slice(Int64, Int64)

Forms a slice out of the given ReadOnlySequence<T>, beginning at start, with length items.
Slice(Int64, SequencePosition)

Forms a slice out of the current ReadOnlySequence<T>, beginning at start and ending at end (exclusive).
Slice(SequencePosition)

Forms a slice out of the current ReadOnlySequence<T>, beginning at a specified sequence position and continuing to the end of the read-only sequence.
Slice(SequencePosition, Int32)

Forms a slice out of the current ReadOnlySequence<T>, beginning at start, with length items.
Slice(SequencePosition, Int64)

Forms a slice out of the current ReadOnlySequence<T>, beginning at start, with length items.
Slice(SequencePosition, SequencePosition)

Forms a slice out of the current ReadOnlySequence<T>, beginning at start and ending at end (exclusive).
ToString()

Returns a string that represents the current sequence.
TryGet(SequencePosition, ReadOnlyMemory<T>, Boolean)

Tries to retrieve the next segment after position and returns a value that indicates whether the operation succeeded.

Extension Methods

CopyTo<T>(ReadOnlySequence<T>, Span<T>)

Copies the ReadOnlySequence<T> to the specified Span<T>.
PositionOf<T>(ReadOnlySequence<T>, T)

Returns the position of the first occurrence of item in the ReadOnlySequence<T>.
ToArray<T>(ReadOnlySequence<T>)

Converts the ReadOnlySequence<T> to an array.
