Nuts - BoltDB Utilities

A collection of BoltDB utilities.

Path Prefix Scans

The prefix scanning functions SeekPathConflict and SeekPathMatch facilitate maintenance and access to buckets of paths supporting variable elements with exclusive matches. Paths are / delimited, must begin with a /, and elements beginning with : or * are variable.

Examples:

/
/blogs/
/blogs/:blog_id

Variable Elements

Path elements beginning with a : match any single element. Path elements beginning with * match any remaining elements, and therefore must be last.

Examples:

Path:  /blogs/:blog_id
Match: /blogs/someblog

Path:  /blogs/:blog_id/comments/:comment_id/*suffix
Match: /blogs/42/comments/100/edit

Exclusive Matches

Using SeekPathConflict before putting new paths to ensure the bucket remains conflict-free guarantees that SeekPathMatch will never match more than one path.

Examples:

Conflicts: `/blogs/:blog_id`, `/blogs/golang`
Match:     `/blogs/golang`

Conflicts: `/blogs/*`, `/blogs/:blog_id/comments`
Match:     `/blogs/42/comments`
