* refactor: avoid using `collect()` when not needed
and cascade notation
* refactor: The user might expect to be able
to use Default as the type can be
constructed without arguments.
* refactor: using `clone` on type `indextree::NodeId`
which implements the `Copy` trait
* refactor: remove intermediary
variables and use cascade notation
* refactor: using `clone` on type `indextree::NodeId`
which implements the `Copy` trait
* refactor: unneeded `return` statement
* refactor: ok_or_else avoids executing a
function when it's not needed
* refactor: dereferenced by the compiler
* refactor: user enumeration for index
* refactor: using `clone` on type `usize`
which implements the `Copy` trait
* refactor: useless conversion to the
same type: `&str`
* refactor: The user might expect to be able use Default
as type can be constructed without arguments
* refactor: The user might expect to be able use Default
as type can be constructed without arguments
* fix: rust formating with fmt
* fix: conflict default implementation
