Add locale-specific ellipsis to a string.
Arguments
- stringis any- String.tor a 2-element list of- String.tbetween which the ellipsis is inserted.
- backendis any module that includes- use Cldrand therefore is a- Cldrbackend module. The default is- Cldr.default_backend!/0. Note that- Cldr.default_backend!/0will raise an exception if no- :default_backendis configured under the- :ex_cldrkey in- config.exs.
