Quick Example
from fptk.core.func import pipe
from fptk.adt.option import Some, NOTHING
from fptk.adt.result import Ok, Err
# Compose transformations
result = pipe(5, lambda x: x + 1, lambda x: x * 2) # 12
# Handle absence explicitly
name = Some("alice").map(str.upper).unwrap_or("anonymous") # "ALICE"
# Type-safe error handling
def parse(s: str) -> Result[int, str]:
try:
return Ok(int(s))
except ValueError:
return Err(f"invalid: {s}")
parse("42").map(lambda x: x * 2) # Ok(84)
