Changelog

Sourced from nom's changelog.

Added

• take_until1 combinator
• more to_owned implementations
• fail: a parser that always fail, useful as default condition in other combinators
• text to number parsers: in the character::streaming and character::complete modules, there are parsers named i8, u16, u32, u64, u128 and u8 ,u16, u32, u64, u128 that recognize decimal digits and directly convert to a number in the target size (checking for max int size)

Removed

• now that function combinators are the main way to write parsers, the old macro combinators are confusing newcomers. THey have been removed
• the BitSlice input type from bitvec has been moved into the nom-bitvec crate. nom does not depend on bitvec now
• regex parsers have been moved into the nom-regex crate. nom does not depend on regex now
• ErrorKind::PArseTo was not needed anymore

Changed

• relax trait bounds
• some performance fixes
• split_at_position* functions should now be guaranteed panic free
• the lexical-core crate used for float parsing has now been replaced with minimal-lexical: the new crate is faster to compile, faster to parse, and has no dependencies

Fixed

• infinite loop in escaped combinator
• many_m_n now fails if min > max

6.2.1 - 2021-06-23
