Module stringsext::finding

Store string-findings and prepare them for output.

Structs

• Finding
  Finding represents a valid result string decoded to UTF-8 with it’s original location and its original encoding in the input stream.

Enums

• Precision
  Used to express the precision of Finding::position when the algorithm can not determine its exact position.

Constants

• OUTPUT_BUF_LEN
  OUTPUT_BUF_LEN needs to be long enough to hold all findings that are decoded to UTF-8 in scan::scan(). To estimate the space needed to receive all decodings in UTF-8, the worst case - Asian like EUC_JP - has to be taken into consideration: Therefor, in order to avoid output buffer overflow, OUTPUT_BUF_LEN should be at least twice as big as INPUT_BUF_LEN. You can also check the minimum length with Decoder::max_utf8_buffer_length_without_replacement. Unfortunately this can not be done programmatically, because output_buffer is a statically allocated array.
• OUTPUT_LINE_METADATA_LEN
  Extra space in bytes for ByteCounter and encoding-name when Finding::print() prints a Finding.
