Struct AssertPathGuard 

pub struct AssertPathGuard<'a> { /* private fields */ }

The guard returned by AssertPath::__guard, which pops the last segment when dropped.

Methods from Deref<Target = AssertPath>

pub fn __guard( &mut self, segment: impl Into<Cow<'static, str>>, ) -> AssertPathGuard<'_>

Internal method to push a new segment to the path, returning a guard that will pop it when dropped.

This is used by the derive macro to track the current path during comparisons.

Example

let mut p = assert_eq::AssertPath::new();
let mut _g1 = p.__guard(".x");
assert_eq!(format!("{:?}", &*_g1), ".x");
{
    let mut _g2 = _g1.__guard(".y");
    assert_eq!(format!("{:?}", &*_g2), ".x → .y");
}
drop(_g1);
assert_eq!(format!("{p:?}"), "<root>");

Trait Implementations

impl Deref for AssertPathGuard<'_>

type Target = AssertPath

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl DerefMut for AssertPathGuard<'_>

fn deref_mut(&mut self) -> &mut Self::Target

Mutably dereferences the value.

impl Drop for AssertPathGuard<'_>

fn drop(&mut self)

Executes the destructor for this type.
