Struct libdata::column::FlowTags

pub struct FlowTags(_);

A reference counted handle to Tags

This is an easily clonable handle towards Tags. The Tags inside can be modified.

Note that comparison and hash identity is based on the address of the tags. Eg. it doesn't matter what they contain, only the handles referencing the same tags are considered equal and the hash and comparison order doesn't change when modifying the content. This allows using the FlowTags as an unique handle to a flow.

Due to the Defer trait it can be manipulated simply as the internal RefCell<Tags>.

Methods
