Core regular expression match methods

Required Methods

fn pattern_match_result( &self, pattern: &str, case_insensitive: bool, ) -> Result<bool, Error>

Apply a regular expression match on the current string If the regex doesn’t compile it will return an error

Provided Methods

fn pattern_match(&self, pattern: &str, case_insensitive: bool) -> bool

Apply a regular expression match on the current string with a boolean case_insensitive flag NB: If the regex doesn’t compile it will return false

fn pattern_match_ci(&self, pattern: &str) -> bool

if the pattern does not match the source string or the regex fails

fn pattern_match_cs(&self, pattern: &str) -> bool

Simple case-sensitive regex-compatible match method that will return false if the pattern does not match the source string or the regex fails

Implementations on Foreign Types

impl PatternMatch for str

Implement regular expression match and replace methods for str and owned String

fn pattern_match_result( &self, pattern: &str, case_insensitive: bool, ) -> Result<bool, Error>

Simple regex-compatible match method that will return an optional boolean

• Some(true) means the regex is valid and the string matches
• Some(false) means the regex is valid and the string does not match
• None means the regex is not valid and can this not be evaluated Only the pattern_match_result needs to be implemented

impl PatternMatch for [&str]

Boolean methods to match a pattern within an array of strings

fn pattern_match_result( &self, pattern: &str, case_insensitive: bool, ) -> Result<bool, Error>

The regex is only compiled when validating an array of strings

impl PatternMatch for [String]

Boolean methods to match a pattern within an array of strings

fn pattern_match_result( &self, pattern: &str, case_insensitive: bool, ) -> Result<bool, Error>

The regex is only compiled when validating an array of strings
