Functions ¶
func CompressTxOutAmount ¶
CompressTxOutAmount compresses the passed amount according to the domain specific compression algorithm described above.
func DecodeCompressedScriptSize ¶
DecodeCompressedScriptSize treats the passed serialized bytes as a compressed script, possibly followed by other data, and returns the number of bytes it occupies taking into account the special encoding of the script size by the domain specific compression algorithm described above.
func DecompressScript ¶
DecompressScript returns the original script obtained by decompressing the passed compressed script according to the domain specific compression algorithm described above.
NOTE: The script parameter must already have been proven to be long enough to contain the number of bytes returned by DecodeCompressedScriptSize or it will panic. This is acceptable since it is only an internal function.
func DecompressTxOutAmount ¶
DecompressTxOutAmount returns the original amount the passed compressed amount represents according to the domain specific compression algorithm described above.
func DeserializeVLQ ¶
DeserializeVLQ deserializes the provided variable-length quantity according to the format described above. It also returns the number of bytes deserialized.
func PutCompressedScript ¶
PutCompressedScript compresses the passed script according to the domain specific compression algorithm described above directly into the passed target byte slice. The target byte slice must be at least large enough to handle the number of bytes returned by the compressedScriptSize function or it will panic.
func PutVLQ ¶
putVLQ serializes the provided number to a variable-length quantity according to the format described above and returns the number of bytes of the encoded value. The result is placed directly into the passed byte slice which must be at least large enough to handle the number of bytes returned by the serializeSizeVLQ function or it will panic.
