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

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.

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.

Reader utility for combining multiple readers

Reader utility for strings.

Writer utility for buffering string chunks.

Copies from src to dst until either EOF (null) is read from src or an error occurs. It resolves to the number of bytes copied or rejects with the first error encountered while copying.

Copy N size at the most. If read size is lesser than N, then returns nread

Turns a Reader into an async iterator.

Turns a ReaderSync into an iterator.

Read Reader r until EOF (null) and resolve to the content as Uint8Array.

Synchronously reads ReaderSync r until EOF (null) and returns the content as Uint8Array.

Read delimited bytes from a Reader.

Create a Reader from a ReadableStreamDefaultReader.

Read big endian 32bit integer from BufReader

Read strings line-by-line from a Reader.

Read big endian 64bit long from BufReader

Read a range of bytes from a file or other resource that is readable and seekable. The range start and end are inclusive of the bytes within that range.

Read a range of bytes synchronously from a file or other resource that is readable and seekable. The range start and end are inclusive of the bytes within that range.

Read big endian 16bit short from BufReader

Read Reader chunk by chunk, splitting based on delimiter.

Slice number into 64bit big endian byte array

Create a ReadableStream of Uint8Arrays from a Reader.

Create a WritableStream from a Writer.

Write all the content of the array buffer (arr) to the writer (w).

Synchronously write all the content of the array buffer (arr) to the writer (w).

An abstract interface which when implemented provides an interface to close files/resources that were previously opened.
