Struct TransactionResult 

pub struct TransactionResult { /* private fields */ }

Wrapper around LiteSVM’s TransactionMetadata with helper methods for testing

This struct provides convenient methods for analyzing transaction results, including log inspection, compute unit tracking, and success assertions.

Example

let result = svm.send_instruction(ix, &[&signer])?;
result.assert_success();
assert!(result.has_log("Transfer complete"));
println!("Used {} compute units", result.compute_units());

Implementations

impl TransactionResult

pub fn new( result: TransactionMetadata, instruction_name: Option<String>, ) -> Self

Create a new TransactionResult wrapper for successful transaction

Arguments

• result - The transaction metadata from LiteSVM
• instruction_name - Optional name of the instruction for debugging

pub fn new_failed( error: String, result: TransactionMetadata, instruction_name: Option<String>, ) -> Self

Create a new TransactionResult wrapper for failed transaction

Arguments

• error - The error message
• result - The transaction metadata from LiteSVM
• instruction_name - Optional name of the instruction for debugging

pub fn assert_success(&self) -> &Self

Assert that the transaction succeeded, panic with logs if it failed

Returns

Returns self for chaining

Example

result.assert_success();

pub fn is_success(&self) -> bool

Check if the transaction succeeded

Returns

true if the transaction succeeded, false otherwise

pub fn error(&self) -> Option<&String>

Get the error message if the transaction failed

Returns

The error message if the transaction failed, None otherwise

pub fn logs(&self) -> &[String]

Get the transaction logs

Returns

A slice of log messages

pub fn has_log(&self, message: &str) -> bool

Check if the logs contain a specific message

Arguments

• message - The message to search for

Returns

true if the message is found in the logs, false otherwise

pub fn find_log(&self, pattern: &str) -> Option<&String>

Find a log entry containing the specified text

Arguments

• pattern - The pattern to search for

Returns

The first matching log entry, or None

pub fn compute_units(&self) -> u64

Get the compute units consumed

Returns

The number of compute units consumed

pub fn print_logs(&self)

Print the transaction logs

pub fn inner(&self) -> &TransactionMetadata

Get the inner TransactionMetadata for direct access

Trait Implementations

impl Debug for TransactionResult
