Struct Unicode.Rune
Representation of a Unicode character as a code point.
Namespace: Unity.Collections
Syntax
public struct RuneConstructors
Rune(Int32)
Initializes and returns an instance of Rune.
Declaration
public Rune(int codepoint)Parameters
| Type | Name | Description |
|---|---|---|
| Int32 | codepoint | The code point. |
Remarks
You are responsible for the code point being valid.
Fields
value
The code point.
Declaration
public int valueField Value
| Type | Description |
|---|---|
| Int32 | The code point. |
Methods
Equals(Object)
Returns true if the value stored in this Rune is equal to an object.
Declaration
[ExcludeFromBurstCompatTesting("Takes managed object")]
public override bool Equals(object obj)Parameters
| Type | Name | Description |
|---|---|---|
| Object | obj | An object to compare with. |
Returns
| Type | Description |
|---|---|
| Boolean | True if the value stored in this Rune is equal to the object. |
Overrides
Remarks
Can only be equal if the object is itself a Rune.
GetHashCode()
A hash used for comparisons.
Declaration
public override int GetHashCode()Returns
| Type | Description |
|---|---|
| Int32 | A unique hash code. |
Overrides
IsDigit(Unicode.Rune)
Returns true if a rune is a numerical digit character.
Declaration
public static bool IsDigit(Unicode.Rune r)Parameters
| Type | Name | Description |
|---|---|---|
| Unicode.Rune | r | The rune. |
Returns
| Type | Description |
|---|---|
| Boolean | True if the rune is a numerical digit character. |
LengthInUtf8Bytes()
Returns the number of bytes required to encode this rune as UTF-8.
Declaration
public int LengthInUtf8Bytes()Returns
| Type | Description |
|---|---|
| Int32 | The number of bytes required to encode this rune as UTF-8. If the rune's codepoint is invalid, returns 4 (the maximum possible encoding length). |
Operators
Equality(Unicode.Rune, Unicode.Rune)
Evaluates if one is equal to the other.
Declaration
public static bool operator ==(Unicode.Rune lhs, Unicode.Rune rhs)Parameters
| Type | Name | Description |
|---|---|---|
| Unicode.Rune | lhs | The left-hand side |
| Unicode.Rune | rhs | The right-hand side |
Returns
| Type | Description |
|---|---|
| Boolean | True if the left-hand side's is equal to the right-hand side's. |
Implicit(Char to Unicode.Rune)
Returns a rune.
Declaration
public static implicit operator Unicode.Rune(char codepoint)Parameters
| Type | Name | Description |
|---|---|---|
| Char | codepoint | A code point. |
Returns
| Type | Description |
|---|---|
| Unicode.Rune | A rune. |
Remarks
Because a char is 16-bit, it can only represent the first 2^16 code points, not all 1.1 million.
Inequality(Unicode.Rune, Unicode.Rune)
Evaluates if one is not equal to the other.
Declaration
public static bool operator !=(Unicode.Rune lhs, Unicode.Rune rhs)Parameters
| Type | Name | Description |
|---|---|---|
| Unicode.Rune | lhs | The left-hand side |
| Unicode.Rune | rhs | The right-hand side |
Returns
| Type | Description |
|---|---|
| Boolean | True if the left-hand side's is not equal to the right-hand side's. |
