Module strings 

Macros

rumtk_format

Creates a CompactString using interpolation of runtime expressions.

Structs

CompactString

A CompactString is a compact string type that can be used almost anywhere a String or str can be used.

GraphemeStr

The equivalent to a stringview but at the grapheme level. Meaning, we can use this view to iterate through a string at the full UTF8 implementation

Constants

DOT_STR

EMPTY_STRING

EMPTY_STRING_OPTION

READABLE_ASCII

Traits

AsStr

CompactStringExt

A trait that provides convenience methods for creating a CompactString from a collection of items. It is implemented for all types that can be converted into an iterator, and that iterator yields types that can be converted into a str.

RUMArrayConversions

RUMStringConversions

StringLike

StringUtils

ToCompactString

A trait for converting a value to a CompactString.

Functions

basic_escape

Escape UTF-8 characters in UTF-8 string that are beyond ascii range

count_tokens_ignoring_pattern

escape

Turn UTF-8 character into escaped character sequence as expected in HL7

filter_ascii

Removes all non ASCII and all non printable characters from string.

filter_non_printable_ascii

Removes all non ASCII and all non printable characters from string.

get_grapheme_collection

Return vector of graphemes from starting spot up until we find the end grapheme.

get_grapheme_string

Get the grapheme block and concatenate it into a newly allocated RUMString.

is_ascii_str

Checks if a given string is fully ASCII or within the ASCII range.

is_escaped_str

Checks if an input string is already escaped. The idea is to avoid escaping the escaped string thus making it a nightmare to undo the escaping later on.

is_printable_char

Returns whether a character is in the ASCII printable range.

try_decode

Implements decoding this string from its auto-detected encoding to UTF-8. Failing that we assume the string was encoded in UTF-8 and return a copy.

try_decode_with

Implements decoding this string from a specific encoding to UTF-8.

unescape

Turn escaped character sequence into the equivalent UTF-8 character This function accepts \o, \x and \u formats. This function will also attempt to unescape the common C style control characters. Anything else needs to be expressed as hex or octal patterns with the formats above.

unescape_string

This function will scan through an escaped string and unescape any escaped characters. We collect these characters as a byte vector. Finally, we do a decode pass on the vector to re-encode the bytes hopefully right into a valid UTF-8 string.
