Classes

c
Buffer
deprecated

A variable-sized buffer of bytes with read() and write() methods.

c
BufferFullError
deprecated
c
BufReader
deprecated
c
BufWriter
deprecated

BufWriter implements buffering for an deno.Writer object. If an error occurs writing to a Writer, no more data will be accepted and all subsequent writes, and flush(), will return the error. After all data has been written, the client should call the flush() method to guarantee all data has been forwarded to the underlying deno.Writer.

c
BufWriterSync
deprecated

BufWriterSync implements buffering for a deno.WriterSync object. If an error occurs writing to a WriterSync, no more data will be accepted and all subsequent writes, and flush(), will return the error. After all data has been written, the client should call the flush() method to guarantee all data has been forwarded to the underlying deno.WriterSync.

c
LimitedReader
deprecated
c
MultiReader
deprecated

Reader utility for combining multiple readers

c
PartialReadError
deprecated
c
StringReader
deprecated

Reader utility for strings.

c
StringWriter
deprecated

Writer utility for buffering string chunks.
