What function does として have in this sentence


I read the definition of 信用:

> 人の言動や物事を間違いないとして，受け入れること

I have looked around a bit and found [What does verb+とする
mean?](https://japanese.stackexchange.com/questions/34137/what-does-
verb%e3%81%a8%e3%81%99%e3%82%8b-mean) but it only covers "dictionary verb form
+ とする"

This one is after a negative «ない», so I wonder if they are different.

So far I understand the sentence as «to accept the word and «thing» of a
person and do so with no doubts».




As the comment points out, this is the compound particle として, meaning
something like "assume". Here is the entry given by A Dictionary of
Intermediate Japanese Grammar, page 518:

So here it means something like "to take the speech and conduct or other
things **as the truth** and accept it"
