pub struct Scanner<I: Input, S: Splitter> { /* private fields */ }
Expand description
Like a BufReader
but with a growable buffer.
Successive calls to the scan
method will step through the ‘tokens’
of a file, skipping the bytes between the tokens.
Scanning stops unrecoverably at EOF, the first I/O error, or a token too
large to fit in the buffer. When a scan stops, the reader may have
advanced arbitrarily far past the last token.
Current column number (byte offset, not char offset)
Reset the scanner such that it behaves as if it had never been used.
Advance the Scanner to next token.
Return the token as a byte slice.
Return None
when the end of the input is reached.
Return any error that occurs while reading the input.
Formats the value using the given formatter.
