Function lexical_core::f64toa_slice

pub fn f64toa_slice<'a>(value: f64, bytes: &'a mut [u8]) -> &'a mut [u8]

Serializer for a number-to-string conversion using Rust slices.

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

If the buffer is not of sufficient size (see the constants named MAX_*_SIZE in the lexical_core crate), this function will panic (and call abort). You must provide a slice of sufficient length. The data in the slice may be uninitialized, these values are never read, only written to.

• value - Number to serialize.
• bytes - Slice containing a numeric string.

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 MAX_*_SIZE elements, using the proper constant for the serialized type from the lexical_core crate root.
