Use Case

As a BSON and driver user
I want to ensure strings that represent longs only contain valid digits and no overflows
So that int64s are constructed from proper digit sequences.

User Impact

• New opt-in feature API

Dependencies

• None

Unknowns

None.

Acceptance Criteria

Implementation Requirements

• Add a new static method to the Long class fromStringStrict that throws when the input contains invalid characters, whitespace or overflows
  • Long.fromStringStrict(str: string, unsigned?: boolean, radix?: number): Long
  • The method must support radixes from 2 through 36 inclusive
  • radix is an optional parameter that must default to 10
  • The method will return the Long representation if it is valid and throw an error if it is not.

Testing Requirements

• Test valid and invalid inputs

Documentation Requirements

• Put API docs on {{Long.fromStringStrict }}with example usage

Follow Up Requirements

• In v7 (next BSON major) NODE-5638 Long.fromString Strict will be called inside Long.fromString
