A printer trait.

The printer prints messages for a test result.

Required Methods

fn print_loading(&self, is_done: bool)

Prints the “Loading tests …” message.

fn print_running_test( &self, idents: &Vec<String>, ident: &String, is_done: bool, is_ok: bool, )

Prints the test running with the test identifier.

This method prints “ok” for the test success or “FAILED” for the test failure if the test is done, otherwise “FAILED”.

fn print_empty_line(&self)

Prints an empty line.

fn print_successes(&self)

Prints the “Successes:” message.

fn print_failures(&self)

Prints the “Failures:” message.

fn print_test_result( &self, idents: &Vec<String>, ident: &String, test_result: &TestResult, ) -> Result<()>

Prints the test result with data from the standard output and the standard error.

fn print_test_counts(&self, passed_test_count: usize, failed_test_count: usize)

Prints the number of passed tests and the number of failed tests.

fn print_lf_for_error(&self)

Prints the newline character for an occurred error.

In older versions of Rust, dyn compatibility was called "object safety".
