§attr - static paths for Rust

Structs§

Identity
The Identity is the end of a path and provides the point where input equals output and we start returning. It’s necessary for recursive path traversal, but generally not to be used in user code.
InsecurePath
A path path describing how to retrieve a value at a point, and then recursive down the rest of the path.
MapPath
A path that describes a mapping operation, which later application of a subpath.
Path
A plain path describing how to retrieve a value at a point, and then recursive down the rest of the path.

Traits§

Attr
Direct access to an attribute of a type.
IndexableAttr
Access to a part of the attribute by index
InsecureAttr
Direct, possibly failing access to an attribute of a type.
InsecureIndexableAttr
Access to a part of the attribute by index, where access can fail
InsecureIterableAttr
Insecure variant of iteration over an attribute
IterableAttr
Iteration over an attribute
Traverse
Recursive path traversal

Functions§

retrieve
retrieve is the starting point of a path that always returns a value.
retrieve_insecure
retrieve_insecure is the starting point of a path that is not always present. For that reason, it returns a Result indicating the success of the path operation.

Type Aliases§

Result
In case of failed traversals, this Result type is returned.
