|
|
|
|

|
|
* [Go builtin types](#go-builtin-types)
|
|
* [Go structs](#go-structs)
|
|
* [Go structs with "keyasint" struct tag](#go-structs-with-keyasint-struct-tag)

|
|
|
|
## Go builtin types
|
|
|
|
Benchmarks use data representing the following values:

|
|
* Float: `-4.1`
|
|
* Byte string: `h'0102030405060708090a0b0c0d0e0f101112131415161718191a'`
|
|
* Text string: `"The quick brown fox jumps over the lazy dog"`
|
|
* Array: `[1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26]`
|
|
* Map: `{"a": "A", "b": "B", "c": "C", "d": "D", "e": "E", "f": "F", "g": "G", "h": "H", "i": "I", "j": "J", "l": "L", "m": "M", "n": "N"}}`

## Go structs
|
|
|
|
Benchmarks use struct and map[string]interface{} representing the following value:
|
|
|
|
```
|
|
{
|
|
"T": true,
|
|
"Ui": uint(18446744073709551615),
|
|
"I": -1000,
|
|
"F": -4.1,
|
|
"B": []byte{1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26},
|
|
"S": "The quick brown fox jumps over the lazy dog",
|
|
"Slci": []int{1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26},
|
|
"Mss": map[string]string{"a": "A", "b": "B", "c": "C", "d": "D", "e": "E", "f": "F", "g": "G", "h": "H", "i": "I", "j": "J", "l": "L", "m": "M", "n": "N"},

## Go structs with "keyasint" struct tag
|
|
|
|
Benchmarks use struct (with keyasint struct tag) and map[int]interface{} representing the following value:
|
|
|
|
```
|
|
{
|
|
1: true,
|
|
2: uint(18446744073709551615),
|
|
3: -1000,
|
|
4: -4.1,
|
|
5: []byte{1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26},
|
|
6: "The quick brown fox jumps over the lazy dog",
|
|
7: []int{1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26},
|
|
8: map[string]string{"a": "A", "b": "B", "c": "C", "d": "D", "e": "E", "f": "F", "g": "G", "h": "H", "i": "I", "j": "J", "l": "L", "m": "M", "n": "N"},
|
|
}
|
|
```
|
|
|
|
Struct type with keyasint struct tag is used to handle CBOR map with integer keys.
|
|
|
|
```
|
|
type T struct {
|
|
T bool `cbor:"1,keyasint"`
|
|
Ui uint `cbor:"2,keyasint"`
|
|
I int `cbor:"3,keyasint"`
|
|
F float64 `cbor:"4,keyasint"`
|
|
B []byte `cbor:"5,keyasint"`
|
|
S string `cbor:"6,keyasint"`
|
|
Slci []int `cbor:"7,keyasint"`
|
|
Mss map[string]string `cbor:"8,keyasint"`
|
|
}

## Go structs with "toarray" struct tag
|
|
|
|
Benchmarks use struct (with toarray struct tag) and []interface{} representing the following value:
|
|
|
|
```
|
|
[
|
|
true,
|
|
uint(18446744073709551615),
|
|
-1000,
|
|
-4.1,
|
|
[]byte{1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26},
|
|
"The quick brown fox jumps over the lazy dog",
|
|
[]int{1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26},
|
|
map[string]string{"a": "A", "b": "B", "c": "C", "d": "D", "e": "E", "f": "F", "g": "G", "h": "H", "i": "I", "j": "J", "l": "L", "m": "M", "n": "N"}
|
|
]
|
|
```
|
|
|
|
Struct type with toarray struct tag is used to handle CBOR array.
|
|
|
|
```
|
|
type T struct {
|
|
_ struct{} `cbor:",toarray"`
|
|
T bool
|
|
Ui uint
|
|
I int
|
|
F float64
|
|
B []byte
|
|
S string
|
|
Slci []int
|
|
Mss map[string]string
|
|
}

## COSE data

|
|
|
Benchmarks use COSE data from https://tools.ietf.org/html/rfc8392#appendix-A section A.2
|
|
|
|
```
