Implementations§

impl StringUtils

pub fn guessEncoding( bytes: &[u8], hints: &DecodingHintDictionary ) -> Option<&'static str>

@param bytes bytes encoding a string, whose encoding should be guessed @param hints decode hints if applicable @return name of guessed encoding; at the moment will only guess one of: “SJIS”, “UTF8”, “ISO8859_1”, or the platform default encoding if none of these can possibly be correct

pub fn guessCharset( bytes: &[u8], hints: &DecodingHintDictionary ) -> Option<CharacterSet>

@param bytes bytes encoding a string, whose encoding should be guessed @param hints decode hints if applicable @return Charset of guessed encoding; at the moment will only guess one of: {@link #SHIFT_JIS_CHARSET}, {@link StandardCharsets#UTF_8}, {@link StandardCharsets#ISO_8859_1}, {@link StandardCharsets#UTF_16}, or the platform default encoding if none of these can possibly be correct

const ALIGN: usize = _

The alignment of pointer.

type Init = T

The type for initializers.
