Function sol_anon::utils::realloc_slot

pub fn realloc_slot<'a>(
    slot: &AccountInfo<'a>,
    message: &str,
    inbox: &mut Account<'a, Inbox>,
    sender: &AccountInfo<'a>,
    system_program: &AccountInfo<'a>
) -> Result<()>

Reallocates the slot account if necessary and handles the transfer of lamports.

This function is responsible for:

1. Calculating the required space for the slot based on the message length.
2. Reallocating the slot account if more space is needed.
3. Handling the transfer of lamports to cover rent for the new allocation.
4. Managing any refunds if the new allocation requires less space.

Arguments

• slot - A reference to the slot account info.
• message - A reference to the message string.
• inbox - A mutable reference to the Inbox account.
• sender - A reference to the sender’s account info.
• system_program - A reference to the system program’s account info.

Returns

Returns Ok(()) if the reallocation and transfers are successful, or an error if any operation fails.
