to-buffer

Syntax​

- to-buffer: spec

The spec is a string that can include:

  • type: One of uint8, int8, uint16, int16, uint32, int32, uint64, int64, float32, float64, double, string. Default is uint8.
  • order: Byte order be (big-endian) or le (little-endian). Default is be.

Examples: uint16, type=float32 order=le, string.

Description​

The to-buffer operation converts the input value into a binary buffer and forwards it. It is the inverse of from-buffer. Input can be a number, string, or buffer; for string type the value is written as UTF-8. If the input is an array of values (or buffers), they are concatenated into a single buffer.

Use to-buffer when you need to produce binary data for a downstream operation (for example from-buffer with a different layout, or a device that consumes buffers).

Examples​

  encoded:
    - source: some-value
    - to-buffer: uint16
  floats-le:
    - source: [1.0, 2.0]
    - to-buffer: type=float32 order=le
