Types

type Body

type Body struct {
	// MaxSize is responsible for a maximal body size in case it is being transferred
	// using ordinary Content-Length header, otherwise (e.g. chunked TE) this limit,
	// unfortunately, doesn't work
	MaxSize MaxBodySize
	// MaxChunkSize is responsible for a maximal size of a single chunk being transferred
	// via chunked TE
	MaxChunkSize MaxBodyChunkSize
}

type HTTP

type HTTP struct {
	// ResponseBuffSize is responsible for a response buffer that is being allocated when
	// client connects and is used for rendering the response into it
	ResponseBuffSize ResponseBuffSize
}

type Headers

type Headers struct {
	// Number is responsible for headers map size.
	// Default value is an initial size of allocated headers map.
	// Maximal value is maximum number of headers allowed to be presented
	Number HeadersNumber
	// MaxKeyLength is responsible for maximal header key length restriction.
	MaxKeyLength MaxHeaderKeyLength
	// MaxValueLength is responsible for maximal header value length restriction.
	MaxValueLength MaxHeaderValueLength
	// HeadersValuesSpace is responsible for a maximal space in bytes available for
	// keeping header values in memory.
	// Default value is initial space allocated when client connects.
	// Maximal value is a hard limit, reaching which one client triggers server
	// to response with 431 Header Fields Too Large
	ValueSpace HeadersValuesSpace
	// MaxValuesObjectPoolSize is responsible for a maximal size of string slices object
	// pool
	MaxValuesObjectPoolSize HeadersValuesObjectPoolSize
}

type HeadersNumber

type HeadersNumber struct {
	Default, Maximal int
}

type HeadersValuesObjectPoolSize

type HeadersValuesObjectPoolSize = int

type HeadersValuesSpace

type HeadersValuesSpace struct {
	Default, Maximal int
}

type MaxBodyChunkSize

type MaxBodyChunkSize = int

type MaxBodySize

type MaxBodySize int

type MaxHeaderKeyLength

type MaxHeaderKeyLength = int

type MaxHeaderValueLength

type MaxHeaderValueLength = int

type MaxURLLength

type MaxURLLength int

type Query

type Query struct {
	// MaxLength is responsible for a limit of the query length
	MaxLength int
	// DefaultMapSize is responsible for an initial capacity of query entries map.
	// There is no up limit because:
	//   Maximal number of entries equals to 65536 (math.MaxUint16) divided by
	//   3 (minimal length of query entry) that equals to 21,845.
	//   Worst case: sizeof(int) == 64 and sizeof(unsafe.Pointer) == 64. Then
	//   slice type takes 16 bytes
	//   In that case, we can calculate how much memory AT MOST will be used.
	//   24 bytes (slice type - cap, len and pointer 8 bytes each) + 1 byte
	//   (an array of a single char in best case) + 16 bytes (string type - len
	//   and pointer) + 1 byte (an array of single char in best case)
	//   42 bytes in total for each pair, 917490 bytes in total, that is 896 kilobytes
	//   that is 0.87 megabytes. IMHO that is not that much to care about. In case it
	//   is - somebody will open an issue, or even better, implement the limit by himself
	//   (hope he is lucky enough to find out how to handle with my hand-made DI)
	DefaultMapSize int
