Struct glob::Paths

pub struct Paths { /* private fields */ }

An iterator that yields Paths from the filesystem that match a particular pattern.

Note that it yields GlobResult in order to report any IoErrors that may arise during iteration. If a directory matches but is unreadable, thereby preventing its contents from being checked for matches, a GlobError is returned to express this.

See the glob function for more details.
