Struct Utf8ByteSpan
Points to a span of UTF-8-encoded text in a buffer.
Inherited Members
Namespace: LaunchDarkly.EventSource
Assembly: LaunchDarkly.EventSource.dll
Syntax
public struct Utf8ByteSpanRemarks
This is similar to the Span type in .NET 5. It is used internally by
EventSource to store event data if the stream is using UTF-8 encoding.
If so, reading DataUtf8Bytes will return the same
byte array, to avoid unnecessary copying.
Constructors
Utf8ByteSpan(byte[], int, int)
Constructs a new instance.
Declaration
public Utf8ByteSpan(byte[] data, int offset, int length)Parameters
| Type | Name | Description |
|---|---|---|
| byte[] | data | The byte array containing the data. |
| int | offset | The offset of the first relevant byte of data within the array. |
| int | length | The number of bytes of relevant data within the array. |
Utf8ByteSpan(string)
Constructs a new instance by copying a string.
Declaration
public Utf8ByteSpan(string s)Parameters
| Type | Name | Description |
|---|---|---|
| string | s | A string to convert to UTF-8 bytes. |
Properties
Data
The byte array containing the data. May be null if Length is zero.
Declaration
public byte[] Data { get; }Property Value
| Type | Description |
|---|---|
| byte[] |
Remarks
It is the caller's responsibility not to modify the array.
Length
The number of bytes of relevant data within the array. This may be less than
Data.Length if the span represents a subset of a larger buffer.
Declaration
public int Length { get; }Property Value
| Type | Description |
|---|---|
| int |
Offset
The offset of the first relevant byte of data within the array. This may be greater than zero if the span represents a subset of a larger buffer.
Declaration
public int Offset { get; }Property Value
| Type | Description |
|---|---|
| int |
Methods
Equals(Utf8ByteSpan)
Tests whether the bytes in this span are the same as another span.
Declaration
public bool Equals(Utf8ByteSpan other)Parameters
| Type | Name | Description |
|---|---|---|
| Utf8ByteSpan | other | Another |
Returns
| Type | Description |
|---|---|
| bool | True if the two spans have the same length and the same
data, starting from each one's |
Equals(string)
Tests whether the bytes in this span are the same as the UTF-8 encoding of the specified string.
Declaration
public bool Equals(string s)Parameters
| Type | Name | Description |
|---|---|---|
| string | s | A string. |
Returns
| Type | Description |
|---|---|
| bool | True if the bytes are equivalent. |
Remarks
This method is potentially inefficient and should be used only in testing.
GetString()
Converts the UTF-8 byte data to a string.
Declaration
public string GetString()Returns
| Type | Description |
|---|---|
| string | A new string. |
