Struct TestCaseName 

pub struct TestCaseName(/* private fields */);

The name of a test case within a binary.

This is the identifier for an individual test within a Rust test binary. Test case names are typically the full path to the test function, like module::submodule::test_name.

Implementations

impl TestCaseName

pub fn new(name: &str) -> Self

Creates a new TestCaseName from a string.

pub fn as_str(&self) -> &str

Returns the name as a string.

pub fn as_bytes(&self) -> &[u8]

Returns the name as bytes.

pub fn len(&self) -> usize

Returns the length of the name in bytes.

pub fn is_empty(&self) -> bool

Returns true if the name is empty.

pub fn contains(&self, pattern: &str) -> bool

Returns true if the name contains the given pattern.

pub fn components(&self) -> Split<'_, &str>

Returns an iterator over the :: separated components of this test case name.

Test case names typically follow Rust’s module path syntax, like module::submodule::test_name. This method splits on :: to yield each component.

Examples

use nextest_metadata::TestCaseName;

let name = TestCaseName::new("foo::bar::test_baz");
let components: Vec<_> = name.components().collect();
assert_eq!(components, vec!["foo", "bar", "test_baz"]);

let simple = TestCaseName::new("test_simple");
let components: Vec<_> = simple.components().collect();
assert_eq!(components, vec!["test_simple"]);

pub fn module_path_and_name(&self) -> (Option<&str>, &str)

Splits the test case name into a module path prefix and trailing name.

Returns (Some(module_path), name) if the test case name contains ::, or (None, name) if it doesn’t.

Examples

use nextest_metadata::TestCaseName;

let name = TestCaseName::new("foo::bar::test_baz");
assert_eq!(name.module_path_and_name(), (Some("foo::bar"), "test_baz"));

let simple = TestCaseName::new("test_simple");
assert_eq!(simple.module_path_and_name(), (None, "test_simple"));

Trait Implementations

impl AsRef<str> for TestCaseName

fn as_ref(&self) -> &str

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for TestCaseName

fn clone(&self) -> TestCaseName

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TestCaseName

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for TestCaseName

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for TestCaseName

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

Formats the value using the given formatter.

impl Hash for TestCaseName

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for TestCaseName

fn cmp(&self, other: &TestCaseName) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for TestCaseName

fn eq(&self, other: &TestCaseName) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for TestCaseName

fn partial_cmp(&self, other: &TestCaseName) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for TestCaseName

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for TestCaseName
