isAttrRange

Whether the given type is a forward range of attributes.

Essentially, an attribute range must be a forward range where

each element has the members name, value, and pos
name and value are forward ranges of characters
name and value have the same type
pos is a TextPos

Normally, an attribute range would come from EntityRange.Entity.attributes or DOMEntity.attributes, but as long as a range has the correct API, it qualifies as an attribute range.

template isAttrRange (

) {

alias NameType = ReturnType!((R r) => r.front.name);

alias ValueType = ReturnType!((R r) => r.front.value);

static if(isForwardRange!R && is(typeof(R.init.front.name)) && is(typeof(R.init.front.value)) && is(ReturnType!((R r) => r.front.pos) == TextPos))

enum isAttrRange;

static if(!(isForwardRange!R && is(typeof(R.init.front.name)) && is(typeof(R.init.front.value)) && is(ReturnType!((R r) => r.front.pos) == TextPos)))
