Struct LiteSVMBuilder 

pub struct LiteSVMBuilder { /* private fields */ }

Builder for creating a LiteSVM instance with programs pre-deployed

This provides a more ergonomic way to set up test environments compared to manually creating LiteSVM instances and deploying programs.

Example

use litesvm_utils::LiteSVMBuilder;
use solana_program::pubkey::Pubkey;

// Simple single program setup
let program_id = Pubkey::new_unique();
let program_bytes = include_bytes!("../target/deploy/my_program.so");
let mut svm = LiteSVMBuilder::new()
    .deploy_program(program_id, program_bytes)
    .build();

// Or use the convenience method for single program
let mut svm = LiteSVMBuilder::build_with_program(program_id, program_bytes);

Implementations

impl LiteSVMBuilder

pub fn new() -> Self

Create a new test environment builder

pub fn deploy_program(self, program_id: Pubkey, program_bytes: &[u8]) -> Self

Add a program to be deployed

Programs are deployed in the order they are added.

Arguments

• program_id - The program ID to deploy at
• program_bytes - The compiled program bytes (.so file contents)

Example

builder.deploy_program(program_id, program_bytes)

pub fn build(self) -> LiteSVM

Build the LiteSVM instance with all programs deployed

Returns

Returns the configured LiteSVM instance with all programs deployed

Example

let mut svm = builder.build();

pub fn build_with_program(program_id: Pubkey, program_bytes: &[u8]) -> LiteSVM

Convenience method to quickly set up a single program

This is equivalent to:

LiteSVMBuilder::new()
    .deploy_program(program_id, program_bytes)
    .build()

Arguments

• program_id - The program ID to deploy at
• program_bytes - The compiled program bytes

Returns

Returns a configured LiteSVM instance with the program deployed

Example

let mut svm = LiteSVMBuilder::build_with_program(program_id, program_bytes);

pub fn build_with_programs(programs: &[(Pubkey, &[u8])]) -> LiteSVM

Convenience method to quickly set up multiple programs

Arguments

• programs - A slice of (program_id, program_bytes) tuples

Returns

Returns a configured LiteSVM instance with all programs deployed

Example

let programs = vec![
    (program_id1, program_bytes1),
    (program_id2, program_bytes2),
];
let mut svm = LiteSVMBuilder::build_with_programs(&programs);

Trait Implementations

impl Default for LiteSVMBuilder

fn default() -> Self

Returns the “default value” for a type.
