1maplit 2====== 3 4Container / collection literal macros for `HashMap <https://doc.rust-lang.org/beta/std/collections/struct.HashMap.html>`_, `HashSet <https://doc.rust-lang.org/beta/std/collections/struct.HashSet.html>`_, `BTreeMap <https://doc.rust-lang.org/beta/std/collections/struct.BTreeMap.html>`_, `BTreeSet <https://doc.rust-lang.org/beta/std/collections/struct.BTreeSet.html>`_. 5 6You can use these for convenience. Using them has no other implications. 7 8Please read the `API documentation here`__ 9 10__ https://docs.rs/maplit/ 11 12|build_status|_ |crates|_ 13 14.. |build_status| image:: https://travis-ci.org/bluss/maplit.svg?branch=master 15.. _build_status: https://travis-ci.org/bluss/maplit 16 17.. |crates| image:: http://meritbadge.herokuapp.com/maplit 18.. _crates: https://crates.io/crates/maplit 19 20 21Recent Changes 22-------------- 23 24- 1.0.2 25 26 - Fix usage of the macros through full paths, like `maplit::hashmap!(..)` (#27) 27 28- 1.0.1 29 30 - Fix ``unused_results`` lint in the macros by @povilasb 31 32- 1.0.0 33 34 - maplit 1.0! 35 - Only documentation changes since the last version 36 37- 0.1.6 38 39 - Add macro ``convert_args!`` for composable opt-in conversion of the 40 expressions being used for the maplit macros. 41 42- 0.1.5 43 44 - Add license files correctly 45 - Add crates.io category 46 - Small doc improvements by @seeekr and @sanmai-NL 47 48- 0.1.4 49 50 - Update docs to point to docs.rs 51 52- 0.1.2 53 54 - Now supports more arguments in hashset!{} and hashmap!{} 55 56- 0.1.0 57 58 - Initial release 59 60FAQ 61--- 62 63**Question:** Very large maps take a long time to compile? 64 65**Answer:** Rustc is very slow to compile big expressions with many literals 66(including integers and float literals). Work around this by either 67using explicitly typed literals, or explicitly typed conversions. 68See https://github.com/bluss/maplit/issues/14 for more information. 69 70 71License 72------- 73 74Dual-licensed to be compatible with the Rust project. 75 76Licensed under the Apache License, Version 2.0 77http://www.apache.org/licenses/LICENSE-2.0 or the MIT license 78http://opensource.org/licenses/MIT, at your 79option.
