rust expected named lifetime parameter in solana smart contract with anchor - rust

Question

I am working with Solana smart contracts using the anchor library, I am trying to make a struct that will store an array of public keys of other Solana accounts, but it is giving errors around lifetimes and borrowing the array. Can someone explain to me what is wrong and how to fix it? I am still iffy on how stuff like borrowing and ownership works in rust.
// This is your program's public key and it will update
// automatically when you build the project.
declare_id!("********************************************");
#[program]
mod hello_anchor {
use super::*;
pub fn initialize(ctx: Context<Initialize>, entries: u64, keys: [&[u8]]) -> Result<()> {
ctx.accounts.new_account.entries = entries;
ctx.accounts.new_account.keys = keys;
msg!("Changed entry number to: {}!", entries); // Message will show up in the tx logs
Ok(())
}
}
#[derive(Accounts)]
pub struct Initialize<'info> {
// We must specify the space in order to initialize an account.
// First 8 bytes are default account discriminator,
// next 8 bytes come from NewAccount.data being type u64.
// (u64 = 64 bits unsigned integer = 8 bytes)
#[account(init, payer = signer, space = 8 + 8)]
pub new_account: Account<'info, NewAccount>,
#[account(mut)]
pub signer: Signer<'info>,
pub system_program: Program<'info, System>,
}
#[account]
pub struct NewAccount {
pub entries: u64,
pub keys: [&[u8]],
}
#[account]
pub struct NewEntry {
pubkey: String,
day: u8,
month: u8,
year: u16,
}
