Expand description

Trait for converting integer types to hexadecimal in a buffer

Required Methods§

fn write_hex(self, case: HexCase, buf: &mut [u8; 16]) -> &[u8] ⓘ

Writes the hex representation into buf and returns the written subslice. Digits are right-aligned with leading zeros trimmed.

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
