Struct KeyPathFrom 

pub struct KeyPathFrom<Root> {
    pub path: Vec<KeyPathElement>,
    /* private fields */
}

Partially erased keypath, retaining information about the root type, but erasing the value type

Fields

path: Vec<KeyPathElement>

Implementations

impl<Root> KeyPathFrom<Root>

pub fn prepending<Base>( &self, keypath: &KeyPath<Base, Root>, ) -> KeyPathFrom<Base>

pub fn is_subpath_of(&self, other: &Self) -> bool

Returns whether this subpath is fully contained within other.

In other words, whether other references a field/index/variant within self.

Returns false if both paths are equal.

pub fn downcast<T>(&self) -> KeyPath<Root, T>

Downcast this keypath to include value type. Note that this always succeeds, regardless of the actual value type the path is pointing to, use with caution.

Trait Implementations

impl<Root: Clone> Clone for KeyPathFrom<Root>

fn clone(&self) -> KeyPathFrom<Root>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<Root: Debug> Debug for KeyPathFrom<Root>

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

Formats the value using the given formatter.

impl<T> Display for KeyPathFrom<T>

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

Formats the value using the given formatter.

impl<Root, T> From<KeyPath<Root, T>> for KeyPathFrom<Root>

fn from(value: KeyPath<Root, T>) -> Self

Converts to this type from the input type.

impl<Root, T> PartialEq<KeyPath<Root, T>> for KeyPathFrom<Root>

fn eq(&self, other: &KeyPath<Root, T>) -> 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<Root: PartialEq> PartialEq for KeyPathFrom<Root>

fn eq(&self, other: &KeyPathFrom<Root>) -> 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<Root> Serialize for KeyPathFrom<Root>

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
