Types

type Closer added in v1.4.5 

type Closer struct {
	// contains filtered or unexported fields
}

Closer is a nice utility for closing a group of objects while reporting an error if one occurs.

func (*Closer) Add added in v1.4.5 

func (c *Closer) Add(closer io.Closer)

Add a new object to be closed.

func (*Closer) Close added in v1.4.5 

func (c *Closer) Close() error

Close closes each of the closers add to [c] and returns the first error 

that occurs or nil if no error occurs.

type Errs 

type Errs struct{ Err error }

func (*Errs) Add 

func (errs *Errs) Add(errors ...error)

func (*Errs) Errored 

func (errs *Errs) Errored() bool

type Packer 

type Packer struct {
	Errs

	// The largest allowed size of expanding the byte array
	MaxSize int
	// The current byte array
	Bytes []byte
	// The offset that is being written to in the byte array
	Offset int
}

Packer packs and unpacks a byte array from/to standard values

func (*Packer) CheckSpace 

func (p *Packer) CheckSpace(bytes int)

CheckSpace requires that there is at least bytes of write space left in the byte array. If this is not true, an error is added to the packer

func (*Packer) Expand 

func (p *Packer) Expand(bytes int)

Expand ensures that there is bytes bytes left of space in the byte slice. If this is not allowed due to the maximum size, an error is added to the packer In order to understand this code, its important to understand the difference between a slice's length and its capacity.
