/*!
|
||||
This module contains an implementation of the `term::Terminal` trait.
|
||||
|
||||
The actual implementation is copied almost verbatim from the `term` crate, so
|
||||
this code is under the same license (MIT/Apache).
|
||||
|
||||
The specific reason why this is copied here is to wrap an Arc<TermInfo> instead
|
||||
of a TermInfo. This makes multithreaded sharing much more performant.
|
||||
|
||||
N.B. This is temporary until this issue is fixed:
