Struct Program 

pub struct Program { /* private fields */ }

A lightweight Program wrapper for building instructions in tests.

Simplified API for testing without RPC layer abstractions:

let ix = ctx.program()
    .accounts(my_program::accounts::Transfer { ... })
    .args(my_program::instruction::Transfer { ... })
    .instruction()?;

Implementations

impl Program

pub fn new(program_id: Pubkey) -> Self

Create a new Program instance for the given program ID

pub fn accounts<T: ToAccountMetas>(self, accounts: T) -> InstructionBuilder

Start building an instruction with accounts.

This returns an InstructionBuilder that you can chain with .args() and .instruction().

Example

let ix = ctx.program()
    .accounts(my_program::accounts::Initialize {
        user: user.pubkey(),
        account: data_account,
        system_program: system_program::id(),
    })
    .args(my_program::instruction::Initialize { value: 42 })
    .instruction()?;

pub fn id(&self) -> Pubkey

Get the program ID

Trait Implementations

impl Clone for Program

fn clone(&self) -> Program

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
