I made an object SEQ[T] which member has data of type seq[T]. Also, I want []
operator and converter from SET[T] to seq[T]. Then, it seems that the data
cannot rewrite in proc f of result.data[0] += 1. But this operation is not
related to converter or [] operator because result.data is seq[T] and accessing
[0] is only access of seq[T]. I think, result.data is converted to SEQ[T]. I
don't want to the converter activated in this case. Then, how to do it?
type SEQ*[T] = object
data*:seq[T]
proc initSEQ*[T](n:int):SEQ[T] =
SEQ[T](data:newSeq[T](n))
# [] operator
proc `[]`*[T](self:SEQ[T], i:int):T = self.data[i]
# converter
converter toSEQ*[T](a:seq[T]):SEQ[T] =
SEQ[T](data:a)
proc f*[T](a:SEQ[T]):SEQ[T] =
result = a
result.data[0] += 1 # I don't like to converter activated
when isMainModule:
var a:SEQ[int] = @[1, 2, 3] # I want to define this way by converter
echo f(a)
Run
