PairRange over the object entries, or an empty range if this is not an object.var.byPair
PairRange byPair() @safeGet a forward range over the key-value pairs of this object.
This method returns a PairRange that can be used with std.algorithm functions and other range-based operations without allocating arrays.
Each element is a KeyValuePair struct with:
.key: the key as a string.val: reference to the value as avar
Returns
A
Examples
import std.algorithm : filter, map;
import std.array : array;
var obj;
obj["a"] = 1;
obj["b"] = 2;
auto pairs = obj.byPair.filter!(p => p.val.as!int > 1).map!(p => p.key).array;
assert(pairs == ["b"]);
