Note libcore

Core Library

The Core Library (libcore) complements the Standard Library (libstd) in the following fashion:

• core is automatically 'use'd in any crate, unless you ask for --no-core when running the compiler.
• everything in core will be automatically imported into the crate you're building, again, unless you pass --no-core

(This list should be consistent with the list here: https://docs.google.com/document/d/1nsQP3PQYBjpnwaBklJ-YKhH0YQA-1UgisiW4Qwfvs3A/edit ...)

• "char":

  • "is_ascii" add
  • "is_digit" add

• "str": * "all" * "any" * "bytes" * "bytes_iter" * "char_at" * "char_range_at" * "chars" rename from "to_chars" (analogous to "bytes") * "chars_iter" rename from "iter_chars" (to make the analagous to the iter versions to come) * "chars_loop" rename from "loop_chars" * "concat" * "connect" * "contains" * "ends_with" * "escape" * "escape_char" * "eq" * "find" * "from_byte" rename from "unsafe_from_byte" * "from_bytes" rename from "unsafe_from_bytes" * "from_char" * "from_chars" * "from_cstr" * "hash" * "index" * "is_ascii" * "is_empty" * "is_not_empty" * "is_utf8" * "is_whitespace" * "len":: add (make it an alias for "len_char") because i think people exepect str::len to be character based. E.g. Ruby has "size" := "length" and "bytesize" * "len_bytes" rename from "byte_len" (analogous to "iter_chars", "loop_chars", "push_byte", "push_char") * "len_chars" rename from "char_len" * "lines" * "lines_any" * "lines_iter" * "lteq" * "map" * "pop_byte" * "pop_char" * "push_byte" * "push_bytes" * "push_char" * "replace" * "rindex" * "shift_byte" * "shift_char" * "slice" rename from "safe_slice" * "slice_char" rename from "char_slice" * "slice_unsafe" rename from "slice" * "split": rename from split_func * "split_char" * "split_char_iter": add * "splitn_char": rename from "splitn" * "splitn_char_iter": add * "split_str" * "split_str_iter": add * "starts_with" * "substr" * "substr_all" rename from "loop_chars_sub" (analogous to "substr") * "substr_len_bytes" rename from "byte_len_range" * "substr_len_chars" rename from "char_len_range" * "to_lower" * "to_upper" * "trim" * "trim_left" * "trim_right" * "unshift_char" * "utf8_char_width" * "words" * "words_iter"

• "str":

  • "is_ascii": implement on top of "char::is_ascii", "all"
  • implement "to_upper", "to_lower" on top of "map"
  • add "pure" to a lot of functions
