import VaporVapor is a framework for building server applications, APIs and websites in Swift. It provides a safe, performant and scalable foundation for building large complex backends.
struct FileIOFileIO is a convenience wrapper around SwiftNIO’s NonBlockingFileIO.
@frozen struct StringA Unicode string value that is a collection of characters.
@frozen struct IntA signed integer value type.
@frozen struct Int64A 64-bit signed integer value type.
struct FileChunksWrapper around NIOFileSystem.FileChunks. This can be removed once NIOFileSystem reaches a stable API.

This method respects values in the "ETag" header and is capable of responding 304 Not Modified if the file in question has not been modified since last served. If advancedETagComparison is set to true, the response will have its ETag field set to a byte-by-byte hash of the requested file. If set to false, a simple ETag consisting of the last modified date and file size will be used. This method will also set the "Content-Type" header automatically if an appropriate MediaType can be found for the file’s suffix.
