Package cloudeng.io/algo/codec
import cloudeng.io/algo/codec
Package codec provides support for interpreting byte slices as slices of other basic types such as runes, int64's or strings.
Types
Type Decoder
type Decoder[T any] interface {
Decode(input []byte) []T
}
Decoder represents the ability to decode a byte slice into a slice of some other data type.
Functions
func NewDecoder[T any](fn func([]byte) (T, int), opts ...Option) Decoder[T]
NewDecode returns an instance of Decoder appropriate for the supplied function.
Type Option
type Option func(*options)
Option represents an option accepted by NewDecoder.
Functions
func ResizePercent(percent int) Option
ResizePercent requests that the returned slice be reallocated if the ratio of unused to used capacity exceeds the specified percentage. That is, if cap(slice) - len(slice)) / len(slice) exceeds the percentage new underlying storage is allocated and contents copied. The default value for ResizePercent is 100.
func SizePercent(percent int) Option
SizePercent requests that the initially allocated slice be 'percent' as large as the original input slice's size in bytes. A percent of 25 will divide the original size by 4 for example.
Examples

type Decoder ¶
Decoder represents the ability to decode a byte slice into a slice of some other data type.
Example ¶
package main
import (
"fmt"
"unicode/utf8"
"cloudeng.io/algo/codec"
)
func main() {
decoded := codec.NewDecoder(utf8.DecodeRune).Decode([]byte("日本語"))
fmt.Println(len(decoded))
}
Output: 3
type Option ¶
type Option func(*options)
Option represents an option accepted by NewDecoder.
func ResizePercent ¶
ResizePercent requests that the returned slice be reallocated if the ratio of unused to used capacity exceeds the specified percentage. That is, if cap(slice) - len(slice)) / len(slice) exceeds the percentage new underlying storage is allocated and contents copied. The default value for ResizePercent is 100.
func SizePercent ¶
SizePercent requests that the initially allocated slice be 'percent' as large as the original input slice's size in bytes. A percent of 25 will divide the original size by 4 for example.
