Implementations

impl Wildcard

pub fn new(w: &str) -> Wildcard

Parse a wildcard filter. All strings are valid, so never fails.

pub fn prefix(&self) -> &str

Returns the shortest possible fixed prefix.

If no "%" is in the filter, then the entire string is returned, Otherwise everything up to the "%" is returned, which may be an empty string.

pub fn is_exact(&self) -> bool

returns true if this search can only match a single key.

This only happens when there is no "%" in the filter.

pub fn as_regex(&self) -> Option<Regex>

Returns the regex that matches my wildcard.

Returns None if the prefix is all that's needed, even if it's still a wildcard.

"prefix%suffix" returns Some but prefix% returns None.
