}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§
sourceunsafe fn to_lexical_unchecked<'a>(self, bytes: &'a mut [u8]) -> &'a mut [u8]
unsafe fn to_lexical_unchecked<'a>(self, bytes: &'a mut [u8]) -> &'a mut [u8]
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.
sourcefn to_lexical<'a>(self, bytes: &'a mut [u8]) -> &'a mut [u8]
fn to_lexical<'a>(self, bytes: &'a mut [u8]) -> &'a mut [u8]
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.
