How to use LocatedSpan with my own input type?

LocatedSpan has been designed to wrap any input type. By default it wraps &str and &[u8] but it should work with any other types.

To do so, all you need is to ensure that your input type implements these traits:

  • nom::InputLength
  • nom::Slice
  • nom::InputIter
  • nom::Compare
  • nom::Offset
  • nom::CompareResult
  • nom::FindSubstring
  • nom::ParseTo
  • nom::AsBytes

And ensure that what represents a char in your input type implements nom::FindToken.

Then you may use all the impl_* macros exposed by the library (see the crate documentation).

get_column is not accurate

Your input probably doesn't have ASCII characters only. You'd probably better use get_column_utf8 when your input is contains UTF-8 extensions, having in mind that it is much slower.
