Struct SyncNative 

pub struct SyncNative<'account> {
    pub native_token: &'account AccountView,
    pub rent_sysvar: Option<&'account AccountView>,
}

Given a wrapped / native token account (a token account containing SOL) updates its amount field based on the account’s underlying lamports. This is useful if a non-wrapped SOL account uses system_instruction::transfer to move lamports to a wrapped token account, and needs to have its token amount field updated.

Accounts expected by this instruction:

• Using runtime Rent sysvar

0. [writable] The native token account to sync with its underlying lamports.

• Using Rent sysvar account

0. [writable] The native token account to sync with its underlying lamports.
1. [] Rent sysvar.

Fields

native_token: &'account AccountView

Native Token Account

rent_sysvar: Option<&'account AccountView>

Implementations

impl<'account> SyncNative<'account>

pub const DISCRIMINATOR: u8 = 17

pub const MAX_ACCOUNTS_LEN: usize = 2

Maximum number of accounts expected by this instruction.

The required number of accounts will depend whether the source account has a single owner or a multisignature owner.

pub const DATA_LEN: usize = 1

Instruction data length:

• discriminator (1 byte)

pub fn new( native_token: &'account AccountView, rent_sysvar: Option<&'account AccountView>, ) -> Self

pub fn invoke(&self) -> ProgramResult
