Implementations

impl ExpressionDiff

pub fn from_expressions( expected: &Expression, actual: &Expression, ignore_missing_expected_values: bool, ) -> ExpressionDiff

pub fn name(&self) -> String

pub fn print_test_result(&self, colorize: bool) -> FmtResult

Print this diff to stderr. Intended to be used in a unit test to print the diff when the evaluation result is a TestError::Diff. This is necessary because, by default, an Err result is displayed using its Debug value.

Example: fn test () -> Result<(), TestError> { let tester: PestTester<Rule, MyParser> = PestTester::from_defaults(Rule::root_rule); let res = tester.evaluate_strict(“mytest”); if let Err(TestError::Diff { diff }) = res { diff.print_test_result(); } res }

Trait Implementations

impl Debug for ExpressionDiff

fn fmt(&self, f: &mut Formatter<'_>) -> Result

impl Display for ExpressionDiff

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
