Module pmtiles2::util

Utilities for reading and writing PMTiles archives.

Structs

• MaxZError
  An error indicating that the specified tile id has a z value greater than the maximum allowed z value.
• OffsetLength
  A structure representing a range of bytes within a larger amount of bytes.

Enums

• WriteDirsOverflowStrategy
  Strategies to divide entries into one or multiple leaf directories, when root directory overflows maximum size.

Functions

• compress
  Returns a new instance of std::io::Write that will emit compressed data to the underlying writer.
• compress_all
  Compresses a byte slice and returns the result as a new Vec<u8>.
• compress_asyncasync
  Async version of compress.
• decompress
  Returns a new instance of std::io::Read that will emit uncompressed data from an the underlying reader.
• decompress_all
  Decompresses a byte slice and returns the result as a new Vec<u8>.
• decompress_asyncasync
  Async version of decompress.
• read_directories
  Reads directories (root- & leaf-directories) from a reader and return all entries as a std::collections::HashMap, with the tile-id as the key and the offset & length as the value.
• read_directories_asyncasync
  Async version of read_directories.
• tile_id
  Converts z/x/y coordinates to a tile id.
• write_directories
  Writes root directory to a writer and return bytes of leaf directory section.
• write_directories_asyncasync
  Async version of write_directories.
• zxy
  Converts a tile id to z/x/y coordinates.
