Functions ¶
func SafeRead ¶
SafeRead reads len(data) bytes from reader to data. It also guarantees that if not all data was not read, there is an error, but masks the io.EOF error out if all the data requested was read. In other words, it guarantees there is an error returned, if not all bytes requested were read, and only then there is an error.
func SafeReadAt ¶
func SafeReadAt(reader *MultiReader, data []byte, offset int64) (int, error)
SafeReadAt reads len(data) bytes from reader at offset to data. It also guarantees that if not all data was not read, there is an error, but masks the io.EOF error out if all the data requested was read. In other words, it guarantees there is an error returned, if not all bytes requested were read, and only then there is an error.
Types ¶
type BytesReader ¶
type BytesReader struct {
// contains filtered or unexported fields
}
func NewBytesReader ¶
func NewBytesReader(b []byte) *BytesReader
func (*BytesReader) Append ¶
func (r *BytesReader) Append(data []byte)
func (*BytesReader) Bytes ¶
func (r *BytesReader) Bytes(offset int64, n int) ([]byte, error)
Bytes returns the slice of n bytes at the provided offset. It returns io.EOF if n bytes are not available.
func (*BytesReader) Len ¶
func (r *BytesReader) Len() int
Len returns the number of bytes of the unread portion of the slice.
func (*BytesReader) ReadAt ¶
func (r *BytesReader) ReadAt(b []byte, off int64) (n int, err error)
ReadAt implements the io.ReaderAt interface.
type MultiReader ¶
type MultiReader struct {
// contains filtered or unexported fields
}
MultiReader supports reading from two concatenated readers, which have to be either bytes readers or multi readers. The static typing of the readers (instead of using io.ReaderAt interface) makes this escape analysis compatible: the buffers passed for Read don't escape because of the MultiReader.
func NewMultiReaderFromBytesReader ¶
func NewMultiReaderFromBytesReader(a *BytesReader) *MultiReader
Creates a new MultiReader from an existing BytesReader.
func NewMultiReaderFromBytesReaders ¶
func NewMultiReaderFromBytesReaders(a, b *BytesReader) *MultiReader
Creates a new MultiReader from a pair of existing BytesReaders.
func NewMultiReaderFromMultiReader ¶
func NewMultiReaderFromMultiReader(a *MultiReader, off int64, n int64) *MultiReader
Creates a new MultiReader from an existing MultiReader.
func NewMultiReaderFromMultiReaders ¶
func NewMultiReaderFromMultiReaders(a *MultiReader, off int64, n int64, b *MultiReader) *MultiReader
Creates a new MultiReader from a pair of existing MultiReaders.
func (*MultiReader) Append ¶
func (r *MultiReader) Append(data []byte)
func (*MultiReader) Bytes ¶
func (r *MultiReader) Bytes(offset int64, n int) ([]byte, error)
Bytes returns the slice of n bytes at the provided offset. It returns io.EOF if n bytes are not available.
func (*MultiReader) HasBytesReaders ¶
func (r *MultiReader) HasBytesReaders() bool
Is this MultiReader built from 1+ BytesReaders?
func (*MultiReader) HasMultiReaders ¶
func (r *MultiReader) HasMultiReaders() bool
Is this MultiReader built from 1+ MultiReaders?
func (*MultiReader) Len ¶
func (r *MultiReader) Len() int
func (*MultiReader) ReadAt ¶
func (r *MultiReader) ReadAt(p []byte, offset int64) (n int, err error)
Implements io.ReaderAt
func (*MultiReader) UnpackBytesReaders ¶
func (r *MultiReader) UnpackBytesReaders() (*BytesReader, *BytesReader)
UnpackBytesReaders extracts the BytesReader instance(s) in use by the MultiReader.
func (*MultiReader) UnpackMultiReaders ¶
func (r *MultiReader) UnpackMultiReaders() (*MultiReader, *MultiReader)
UnpackMultiReaders extracts the MultiReader instance(s) in use by the MultiReader.
