Struct poem::test::TestJsonArray

pub struct TestJsonArray<'a>(_);

Available on crate feature test only.

A JSON array.

Implementations

impl<'a> TestJsonArray<'a>

pub fn len(&self) -> usize

Returns the number of elements in the array.

pub fn is_empty(&self) -> bool

Returns true if the array contains no elements.

pub fn get(&self, idx: usize) -> TestJsonValue<'a>

Returns the element at index idx.

pub fn get_opt(&self, idx: usize) -> Option<TestJsonValue<'a>>

Returns the element at index idx, or None if the element does not exists exists.

pub fn iter(&self) -> impl Iterator<Item = TestJsonValue<'a>>

Returns an iterator over the array.

pub fn assert_len(&self, len: usize)

Asserts the array length is equals to len.

pub fn assert_is_empty(&self)

Asserts the array is empty.

pub fn assert_contains(&self, f: impl FnMut(TestJsonValue<'_>) -> bool)

Asserts the array contains values that satisfies a predicate.

pub fn assert_contains_exactly_one(&self, f: impl Fn(TestJsonValue<'_>) -> bool)

Asserts the array contains exactly one value that satisfies a predicate.

Trait Implementations

impl<'a> Clone for TestJsonArray<'a>

fn clone(&self) -> TestJsonArray<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for TestJsonArray<'a>

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

Formats the value using the given formatter.

impl<'a, T> PartialEq<T> for TestJsonArray<'a>where
    T: AsRef<[Value]>,

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

This method tests for self and other values to be equal, and is used by ==.

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

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