Detailed Description

template<size_t N>
struct nros::FixedString< N >

Fixed-capacity null-terminated string.

Wraps a char[N] buffer with safe assignment and query methods. Memory layout is identical to char[N], so the type is C-ABI compatible and can be passed across the runtime boundary by value.

Usage:

nros::FixedString<256> name;
name = "hello world";
printf("%s (len=%zu)\n", name.c_str(), name.length());
