Assembly: fluentsoft.generators.dll, fluentsoft.generators.runtime.dll

Value Arrays

Generates value array of fixed size.

ValueArrayAttribute<T> class

where T : unmanaged

Namespace: Fluentsoft.System
Assembly: fluentsoft.generators.runtime.dll

Marks a struct as a placeholder for value array:

[ValueArray<int>(5)]
public partial struct ValueArrayStruct { }

Remarks

When struct marked by ValueArray attribute, the code generator add folowing members to the struct type
The StructTypeName is a name of struct the ValueArrayAttribute applied to.
The ElementTypeName is a name of array element type.

Example

using Fluentsoft.System;
using Xunit;

Assert.Equal(3, ValueArrayStruct.Length);
Assert.Equal(3 * sizeof(My), sizeof(ValueArrayStruct))

var f = new ValueArrayStruct();
f[0].C = 'A';
f[1].N = 15;
var m1 = f[0];
ref var m2 = ref f[1];
Assert.Equal(f[1].N, m2.N);
m2.N = 38;
Assert.Equa;(38, f[1].N);

Assert.Throws<IndexOutOfRangeException>(() => f[3]);

var st = new MyStruct(stackalloc int[]{1,2,3,4,5});
foreach (var s in st)
{
    Console.WriteLine(s);
}
Assert.Equal(new int[]{1,2,3,4,5}, st.ToArray());

public struct My
{
    public char C;
    public double D;
    public int N;
}

[ValueArray<My>(3)]
public partial struct ValueArrayStruct { }

[ValueArray<int>(5)]
public partial struct MyStruct { }
