Variables ¶

TLV errors.
Functions ¶
func DecodeNNIBlock ¶
DecodeNNIBlock decodes a non-negative integer value from a block.
func DecodeTypeLength ¶
DecodeTypeLength decodes the TLV type, TLV length, and total size of the block from a byte slice.
func DecodeVarNum ¶
DecodeVarNum decodes a non-negative integer value from a wire value.
func EncodeVarNum ¶
EncodeVarNum encodes a non-negative integer value for encoding.
func GetNNIBlockSize ¶
GetNNIBlockSize returns the size that a non-negative integer block will take when encoded.
func IsCritical ¶
IsCritical returns whether a TLV type is critical.
Types ¶
type Block ¶
type Block struct {
// contains filtered or unexported fields
}
Block contains an encoded block.
func DecodeBlock ¶
DecodeBlock decodes a block from the wire.
func EncodeNNIBlock ¶
EncodeNNIBlock encodes a non-negative integer value in a block of the specified type.
func NewEmptyBlock ¶
NewEmptyBlock creates an empty encoded block.
func (*Block) Erase ¶
Erase erases the first subelement of the specified type and returns whether an element was removed.
func (*Block) EraseAll ¶
EraseAll erases all subelements of the specified type and returns the count of elements removed.
func (*Block) Find ¶
Find returns the first subelement of the specified type, or nil if none exists.
func (*Block) Insert ¶
Insert inserts the subelement in order of ascending TLV type, after any subelements of the same TLV type. Note that this assumes subelements are ordered by increasing TLV type.
func (*Block) Reset ¶
func (b *Block) Reset()
Reset clears the encoded wire buffer, value, and subelements of the block.
func (*Block) Subelements ¶
Subelements returns the sub-elements of the block.
