Pattern methods for arrays or vectors only, return vectors of booleans matching each input string

Required Methods

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

Returns result with a vector of tuples with matched status and string slice for an array or vector of strings with a case-insensitive flag or an error if the regex does not compile

fn pattern_matched_pairs_default(&self) -> Vec<(bool, &str)>

Return a default vector of paired tuples if the regular expression fails in pattern_matched_pairs or pattern_matches This has to implemented separately for all other derived methods returning vectors to work correctly

Provided Methods

fn pattern_matched_pairs( &self, pattern: &str, case_insensitive: bool, ) -> Vec<(bool, &str)>

Returns a vector of tuples with matched status and string slice for an array or vector of strings with a case-insensitive flag If the regular expression fails all items will be false

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

Returns result with a vector of boolean matches for an array or vector of strings with case-insensitive flag or an error if the regex does not compile

fn pattern_matches_filtered( &self, pattern: &str, case_insensitive: bool, ) -> Vec<&str>

Returns a filtered vector of matched string slices (&str) with case-insensitive flag

fn pattern_matches_filtered_ci(&self, pattern: &str) -> Vec<&str>

Returns a filtered vector of matched string slices (&str) in case-insensitive mode

fn pattern_matches_filtered_cs(&self, pattern: &str) -> Vec<&str>

Returns a filtered vector of matched string slices (&str) in case-sensitive mode

fn pattern_matches(&self, pattern: &str, case_insensitive: bool) -> Vec<bool>

Returns vector of boolean matches for an array or vector of strings with case-insensitive flag must be reimplemented from pattern_matches_result owing to trait bound constraints on unsized arrays

fn pattern_matches_ci(&self, pattern: &str) -> Vec<bool>

Returns vector of boolean matches for an array or vector of strings in case-insensitive mode

fn pattern_matches_cs(&self, pattern: &str) -> Vec<bool>

Returns vector of boolean matches for an array or vector of strings in case-sensitive mode

Implementations on Foreign Types

impl PatternMatches for [&str]

Multiple match methods for arrays or vectors of &str values

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

Returns an Ok result with a vector of boolean matches for an array or vector of strings with a case-insensitive flag and an error only if the regex fails to compile.

fn pattern_matched_pairs_default(&self) -> Vec<(bool, &str)>

impl PatternMatches for [String]

Multiple match methods for arrays or vectors of strings Implemented separately because of irresolvable Iterator trait bounds rules in Rust 2018 and because both String and &str are normalised to vectors with string references in the return types

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

Returns an Ok result with a vector of boolean matches for an array or vector of strings with a case-insensitive flag and an error only if the regex fails to compile.

fn pattern_matched_pairs_default(&self) -> Vec<(bool, &str)>
