This crate contains pinocchio
helpers to perform cross-program invocations (CPIs) for System program instructions.
Each instruction defines an struct
with the accounts and parameters required. Once all values are set, you can call directly invoke
or invoke_signed
to perform the CPI.
This is a no_std
crate.
Note: The API defined in this crate is subject to change.
Examples
Creating a new account:
// This example assumes that the instruction receives a writable signer `payer_info`
// and `new_account_info` accounts.
CreateAccount {
from: payer_info,
to: new_account_info,
lamports: 1_000_000_000, // 1 SOL
space: 200, // 200 bytes
owner: &spl_token::ID,
}.invoke()?;
Performing a transfer of lamports:
// This example assumes that the instruction receives a writable signer `payer_info`
// account and a writable `recipient_info` account.
Transfer {
from: payer_info,
to: recipient_info,
lamports: 500_000_000, // 0.5 SOL
}.invoke()?;
