Expand description

Trait for numerical types that can be serialized to bytes.

To determine the number of bytes required to serialize a value to string, check the associated constants from a required trait:

Required Methods

Serializer for a number-to-string conversion.

Returns a subslice of the input buffer containing the written bytes, starting from the same address in memory as the input slice.

  • value - Number to serialize.
  • bytes - Buffer to write number to.
Safety

Safe as long as the caller has provided a buffer of at least FORMATTED_SIZE_DECIMAL elements. If a smaller buffer is provided, a buffer overflow is very likely.

Serializer for a number-to-string conversion.

Returns a subslice of the input buffer containing the written bytes, starting from the same address in memory as the input slice.

  • value - Number to serialize.
  • bytes - Buffer to write number to.
Panics

Panics if the buffer is not of sufficient size. The caller must provide a slice of sufficient size. In order to ensure the function will not panic, ensure the buffer has at least FORMATTED_SIZE_DECIMAL elements.
