Functions

deconstruct

void deconstruct(staticMap!(toPointer, Types) ptrs)

Deconstruction support for the <a href="/dext/dext/let">let module</a>.

opEquals

bool opEquals(auto ref const Self other)

Implements equality comparison with other records of the same type. Two records are only considered equal if all fields are equal.

toHash

size_t toHash()

Computes the hashcode of this record based on the hashes of the fields, as well as the field names to avoid collisions with other records with the same number and type of fields.

toString

string toString()

Stringifies and formats all fields.

1 // define a point int 2D space
2 alias Point = Record!(
3     int, "x",
4     int, "y"
5 );
6 
7 auto a = Point( 3, 7 );
8 auto b = Point( 9, 6 );
9 
10 // Euclidean distance
11 auto distance( in Point a, in Point b )
12 {
13     import std.math : sqrt;
14 
15     return sqrt( ( a.x - b.x ) ^^ 2f + ( a.y - b.y ) ^^ 2f );
16 }
17 
18 auto dist = distance( a, b ); // 6.08276
