Methods to split a longer strong on a separator and return a vector of strings, a tuple of two strings or single optional string segment Note some methods may return empty segments in the case of leading, trailing or repeated separators See notes below

Required Methods

fn to_segments(&self, separator: &str) -> Vec<String>

Extract a vector of non-empty strings from a string-like object with a given separator excluding leading, trailing or double separators

fn to_parts(&self, separator: &str) -> Vec<String>

Extract a vector of strings from a string-like object with a given separator

fn to_head(&self, separator: &str) -> String

Extract only the head before the first occurrence of a separator

fn to_first(&self, separator: &str) -> String

Extract only the first segment before the first occurrence of a non-initial separator

fn to_remainder_end(&self, separator: &str) -> String

Extract only the remainder after the first occurrence of a non-initial separator

fn to_last(&self, separator: &str) -> String

Extract only the last segment after the last occurrence of a non-final separator

fn to_remainder_start(&self, separator: &str) -> String

Extract only the beginning before the last segment following the last occurrence of a non-final separator

fn to_end(&self, separator: &str) -> String

Extract only the last segment

fn to_segment(&self, separator: &str, index: i32) -> Option<String>

Extract a string-like segment identified by its index from the components of a string with a given separator e.g. String::from(“10/11/2024”) .to_segment(1) yields “11”

fn to_inner_segment(&self, groups: &[(&str, i32)]) -> Option<String>

fn to_tail(&self, separator: &str) -> String

extract the remainder after the head

fn to_head_tail(&self, separator: &str) -> (String, String)

extract the first and last parts after the first occurrence of the separator

fn to_start_end(&self, separator: &str) -> (String, String)

extract the first and last parts after the last occurrence of the separator

Implementations on Foreign Types

impl ToSegments for str

Implement string segment split and capture method for String

fn to_parts(&self, separator: &str) -> Vec<String>

Splits a string on the exact separator, whether initial, final or repeated. May yield empty segments

fn to_segments(&self, separator: &str) -> Vec<String>

Splits a string on a separator, but only returns an array of non-empty strings skipping leading, trailing or repeated separators that may otherwise yield empty strings

fn to_last(&self, separator: &str) -> String

Extract only the last segment after the last occurrence of a non-final separator

fn to_end(&self, separator: &str) -> String

extract the last segment whether empty or not

fn to_first(&self, separator: &str) -> String

Extract only the first segment before the first occurrence of a non-initial separator

fn to_remainder_end(&self, separator: &str) -> String

Extract only the remainder after the first occurrence of a non-initial separator

fn to_remainder_start(&self, separator: &str) -> String

Extract only the beginning before the last segment following the last occurrence of a non-final separator

fn to_segment(&self, separator: &str, index: i32) -> Option<String>

Extract an indexed segment yielded by splitting a string. A negative index parameter will start from the end

fn to_inner_segment(&self, groups: &[(&str, i32)]) -> Option<String>

extract inner segment via a set of tuples with separators and indices.

fn to_head_tail(&self, separator: &str) -> (String, String)

Extract a tuple of the head and remainder, like split_once but returns Strings

fn to_start_end(&self, separator: &str) -> (String, String)

Extract a tuple of the tail and remainder, like split_once in reverse and returning strings

fn to_head(&self, separator: &str) -> String

fn to_tail(&self, separator: &str) -> String
