lang: Return overflow error from `Lamports` trait operations #2907

Closed acheroncrypto closed 5 months ago

acheroncrypto commented 5 months ago

Problem

Currently, the default behavior of the Lamports methods is to panic on overflow (due to overflow-checks flag).

Summary of changes

Return ProgramError::ArithmeticOverflow in the case of an overflow of Lamports trait methods instead of panicking, giving more flexibility to the developer to gracefully handle overflow situations.
