Attribute Macro clone_spl_program_error

#[clone_spl_program_error]

Proc macro attribute to turn your enum into a Solana Program Error

Adds:

• Clone
• Debug
• Eq
• PartialEq
• thiserror::Error
• num_derive::FromPrimitive
• Into<clone_solana_program::program_error::ProgramError>
• clone_solana_program::decode_error::DecodeError
• clone_solana_program::program_error::PrintProgramError

Optionally, you can add hash_error_code_start: u32 argument to create a unique u32 starting error codes from the names of the enum variants. Notes:

• The error variant will start at this value, and the rest will be incremented by one
• The value provided is only for code readability, the actual error code will be a hash of the input string and is checked against your input

Syntax: #[clone_spl_program_error(hash_error_code_start = 1275525928)] Hash Input: clone_spl_program_error:<enum name>:<variant name> Value: u32::from_le_bytes(<hash of input>[13..17])
