Function glib::file_get_contents

pub fn file_get_contents(filename: impl AsRef<Path>) -> Result<Slice<u8>, Error>

Reads an entire file into allocated memory, with good error checking.

If the call was successful, it returns true and sets contents to the file contents and length to the length of the file contents in bytes. The string stored in contents will be nul-terminated, so for text files you can pass None for the length argument. If the call was not successful, it returns false and sets error. The error domain is G_FILE_ERROR. Possible error codes are those in the FileError enumeration. In the error case, contents is set to None and length is set to zero.

filename

name of a file to read contents from, in the GLib file name encoding

Returns

true on success, false if an error occurred

contents

location to store an allocated string, use g_free() to free the returned string
