type TypeFlag ¶
type TypeFlag byte
TypeFlag is for data structure meta/data flag.
const ( // StringMeta is the flag for string meta. StringMeta TypeFlag = 'S' // StringData is the flag for string data. StringData TypeFlag = 's' // HashMeta is the flag for hash meta. HashMeta TypeFlag = 'H' // HashData is the flag for hash data. HashData TypeFlag = 'h' // ListMeta is the flag for list meta. ListMeta TypeFlag = 'L' // ListData is the flag for list data. ListData TypeFlag = 'l' )
