Typing essentials that make the development process a bit faster.
New: Optional support.
from tyd import * # demo purposes only
value: Optional[str] = "Hello!"
nothing: Optional[str] = None
unwrap(value)
unwrap(nothing) # raises an error because this is None
unwrap_or(value) # "Hello!"
unwrap_or(nothing, "Hello again") # "Hello again"
unwrap_or_else(nothing, lambda: str(10 + 10)) # "20"
# map() essentially transforms the data to another if it's not None
map(value, 100) # 100 (int)
map(nothing, 100) # None
# some other utilities
is_some(value)
is_none(nothing)
