## Function Documentation

## ◆ as_string() [1/2]

const char * osmium::io::as_string | ( | const file_format | format | ) |
| inline noexcept

## ◆ as_string() [2/2]

const char * osmium::io::as_string | ( | file_compression | compression | ) |
| inline

## ◆ begin() [1/2]

InputIterator< Reader > osmium::io::begin | ( | Reader & | reader | ) |
| inline

## ◆ begin() [2/2]

InputIterator< ReaderWithProgressBar > osmium::io::begin | ( | ReaderWithProgressBar & | reader | ) |
| inline

## ◆ end() [1/2]

InputIterator< Reader > osmium::io::end | ( | Reader & |  | ) |
| inline

## ◆ end() [2/2]

InputIterator< ReaderWithProgressBar > osmium::io::end | ( | ReaderWithProgressBar & |  | ) |
| inline

## ◆ make_input_iterator_range()

template<typename TItem , typename TSource >

InputIteratorRange< TSource, TItem > osmium::io::make_input_iterator_range | ( | TSource & | source | ) |

## ◆ make_output_iterator()

template<typename TDest >

OutputIterator< TDest > osmium::io::make_output_iterator | ( | TDest & | destination | ) |

## ◆ operator<<() [1/2]

template<typename TChar , typename TTraits >

std::basic_ostream< TChar, TTraits > & osmium::io::operator<< | ( | std::basic_ostream< TChar, TTraits > & | out,
|  | const file_compression | compression )
| inline

## ◆ operator<<() [2/2]

template<typename TChar , typename TTraits >

std::basic_ostream< TChar, TTraits > & osmium::io::operator<< | ( | std::basic_ostream< TChar, TTraits > & | out,
|  | const file_format | format )
| inline

## ◆ read_file()

template<typename... TArgs>

osmium::memory::Buffer osmium::io::read_file | ( | TArgs &&... | args | ) |

Read contents of the given file into a buffer in one go. Takes the same arguments as any of the Reader constructors.

The buffer can take up quite a lot of memory, so don't do this unless you are working with small OSM files and/or have lots of RAM.

## ◆ supported_pbf_compression_types()

std::vector< std::string > osmium::io::supported_pbf_compression_types | ( |  | ) |
| inline

Get a list of all compression types supported for PBF files.
