PRE DETERMINE THE SIZE OF A STRING

[kevid]

Hi all,

please, is there a way to pre-determine the size (or capacity) of a
string in ruby?

i.e if a have a string "str" , i will set it to contain characters not
more than 10.

No, strings in Ruby are unbounded. If you need that functionality you
will have to create a class which implements this.

(Note: Ruby != C)

Kind regards

Nope, strings are resized dynamically as required. But you could make
your own class which does this.

It could, for example, delegate to an underlying String object,
intercepting calls which could make the string bigger, and either raise
an error or truncate the error if it exceeds the chosen size.

But you likely do not need that
What is your aim ?
