Smart accessors for Rust

crate docs

Overview

There are many sorts of “smart pointers”. They have following things in common:

  • a simple protocol for accessing the data (make some bookkeeping and then give something equivalent to a raw pointer to the data)

  • some nontrivial logic of ownership management

This crate provides “smart accessors”:

  • they aren't concerned with questions of ownership
  • they give a bidirectional view of the data: updating the accessed data can cause a nontrivial change of other data linked with the data being accessed
  • the accessed view can be entirely virtual: it can be constructed only for the duration of the access

For code examples see the docs.

Usage

Simply include

smart_access = "0.7"

in your Cargo.toml.

Variants

The library, although being very small, includes some pluggable components.

For a bare-bones version use

smart_access = { version = "0.7", default-features = false }

But usually you'll want something more convenient.

Accessors for Vec, HashMap and BTreeMap

smart_access = { version = "0.7", default-features = false, features = ["collections", "hashbrown"] }

A maximal no_std and no-alloc variant

smart_access = { version = "0.7", default-features = false, features = ["batch_ct", "detach", "traversal"] }

Versions

  • 0.7.0: Now fully independent of std.
  • 0.6.2: An accessor to the Vec-owned slice + some doc improvements.
  • 0.6.1: Fixed iterator accessors panicking on too large ranges.
  • 0.6.0: Accessors for iterators + get_clone method on the Cps trait.
  • 0.5.4: Accessors for stdlib sets + doc improvements.
  • 0.5.3: A new sort of map accessors (wrapping and_modify(..).or_insert(..)).
  • 0.5.2: Added a macro for forming pathlike types.
  • 0.5.1: Some errors in the documentation fixed. A concrete type of detached paths is now public.
  • 0.5.0: A change in the presentation of the AT struct. The detach feature reworked. Docs now have a version migration guide.

  • 0.4.0: Public API for using access batches as function inputs/outputs.
  • 0.3.0: Public API for using detached accessors as function inputs/outputs.
  • 0.2.2: New feature detach allows one to detach an accessor from the source of the data accessed.
  • 0.2.1: Now really works on no_std.
