Module fastobo::ast[−][src]

Owned syntax tree for the OBO format version 1.4.

OboDoc is the struct acting as the root of the syntax tree. It can be created from a borrowed string slice with either FromStr::from_str or FromSlice::from_slice, from a file with fastobo::from_file, or from a buffered reader with fastobo::from_stream.

About `FromStr`

All types in this module should implement FromStr to allow them to be read from their string serialization. However, some types are simple wrappers for string types (e.g. UnquotedString and QuotedString) and can be constructed from their string value using the From<&str> implementation. Make sure not to confuse how you instantiate these types depending on the content of the string you use.
