-/*
-Package buffer contains buffer and wrapper types for byte slices. It is useful for writing lexers or other high-performance byte slice handling.
-
-The `Reader` and `Writer` types implement the `io.Reader` and `io.Writer` respectively and provide a thinner and faster interface than `bytes.Buffer`.
-The `Lexer` type is useful for building lexers because it keeps track of the start and end position of a byte selection, and shifts the bytes whenever a valid token is found.
-The `StreamLexer` does the same, but keeps a buffer pool so that it reads a limited amount at a time, allowing to parse from streaming sources.
