Module deltachat::tools

Some tools and enhancements to the used libraries, there should be no references to Context and other “larger” entities here.

Structs

• EmailAddress
  Represents an email address, right now just the name@domain portion.
• MailTo
  Struct containing all mailto information

Constants

• BROTLI_BUFSZ 🔒
  Compressor/decompressor buffer size.
• RTLO_CHARACTERS 🔒

Traits

• IsNoneOrEmpty 🔒

Functions

• buf_compress 🔒
  Compresses buf to Vec using brotli. Note that it handles an empty buf as a special value that remains empty after compression, otherwise brotli would add its metadata to it which is not nice because this function is used for compression of strings stored in the db and empty strings are common there. This approach is not strictly correct because nowhere in the brotli documentation is said that an empty buffer can’t be a result of compression of some input, but i think this will never break.
• buf_decompress 🔒
  Decompresses buf to Vec using brotli. See buf_compress() for why we don’t pass an empty buffer to brotli decompressor.
• create_folder 🔒
• create_id 🔒
  Generate an ID. The generated ID should be as short and as unique as possible:
• create_outgoing_rfc724_mid 🔒
  Function generates a Message-ID that can be used for a new outgoing message.
• create_smeared_timestamp 🔒
  Returns a timestamp that is guaranteed to be unique.
• create_smeared_timestamps 🔒
• delete_file 🔒
• delete_files_in_dir
• duration_to_str
  Converts duration to string representation suitable for logs.
• extract_address_from_receive_header 🔒
• extract_grpid_from_rfc724_mid 🔒
  Extract the group id (grpid) from a message id (mid)
• get_abs_path 🔒
  Expand paths relative to $BLOBDIR into absolute paths.
• get_filebytes 🔒
• get_filemeta
  Returns the (width, height) of the given image buffer.
• get_filesuffix_lc
• get_release_timestamp
  Returns the last release timestamp as a unix timestamp compatible for comparison with time() and database times.
• gm2local_offset 🔒
• improve_single_line_input 🔒
  Sanitizes user input
• maybe_add_time_based_warnings 🔒
• maybe_warn_on_bad_time 🔒
• maybe_warn_on_outdated 🔒
• open_file
• open_file_std
• parse_mailto
  Parse mailto urls
• parse_receive_header 🔒
• parse_receive_headers 🔒
  parses “receive”-headers
• read_dir
  Reads directory and returns a vector of directory entries.
• read_file
  Reads the file and returns its context as a byte vector.
• remove_subject_prefix
• single_value 🔒
  If collection contains exactly one element, return this element. Otherwise, return None.
• smeared_time 🔒
  Returns the current smeared timestamp,
• strip_rtlo_characters 🔒
  This method strips all occurrences of the RTLO Unicode character. Why is this needed?
• time 🔒
• timestamp_to_str
  Converts Unix time in seconds to a local timestamp string.
• truncate 🔒
  Shortens a string to a specified length and adds “[…]” to the end of the shortened string.
• truncate_by_lines 🔒
  Shortens a string to a specified line count and adds “[…]” to the end of the shortened string.
• write_file 🔒
  Write a the given content to provided file path.
