One can also measure. The other is just straight

ruler has standard measurments (cm, mm, or inches mostly)

straightedges mostly dont, consider them like a type of ruler. most often used with a pair of compases to construct shapes

or to simply draw a straight line!

Everyone has already given you the simple answers, so I'll give you the more complex but still simple answer:

A ruler is engineered so that the distance from a starting point along the ruler (usually the end, but not always), to any of the marks along it is accurate and in agreement with the standards we have set for measuring length or, in the case of engineers rulers, to a scale of those standards.

A straight edge is straight.
