}Expand description
A path is simply the data describing how to look up a field from a value. This should only be implemented for types that are very cheap to clone, such as references.
Required Associated Types§
type Iter: Iterator<Item = BorrowedSegment<'a>> + Clone
Required Methods§
Sourcefn segment_iter(&self) -> Self::Iter
fn segment_iter(&self) -> Self::Iter
Iterates over the raw “Borrowed” segments.
Provided Methods§
fn concat<T: ValuePath<'a>>(&self, path: T) -> PathConcat<Self, T>
fn eq(&self, other: impl ValuePath<'a>) -> bool
fn can_start_with(&self, prefix: impl ValuePath<'a>) -> bool
fn to_owned_value_path(&self) -> Result<OwnedValuePath, ()>
Dyn Compatibility§
This trait is not dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
