Vague unscrutable error messages on construction of `Container` and `Resource`

[venushastri92]

Describe the problem

using ConcurrentSim
env = Simulation()
Container(env, capacity = 100, level = 31)

Simply running this throws me an error :
UndefVarError: N not defined

Stacktrace:
[1] top-level scope
@ In[1]:4

It might be associated with the container parameter N. Please help me resolve this issue.

Hi! Thanks for reporting this!

For Container you need to specify the data type that would be used explicitly. One of these two options should work for you though:

julia> Container{Int,Int}(env, 100, level = 31)
Resource

julia> Resource(env, 100, level = 31) # implicitly a Int-containing Container
Resource

Of note is that both constructors have capacity as a default argument, not a keyword argument, so Resource(env, capacity = 100, level = 31) would actually raise an error.

Both of these need fixing, so I will leave this issue open:

• better error message when Container is not given a type parameter (maybe simply a better constructor)
• better constructor for when capacity is given as a keyword argument (maybe @kwdef too) for Resource and Container
