Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

uptime: c_long

Seconds since boot

loads: [c_ulong; 3]

1, 5, and 15 minute load averages

totalram: c_ulong

Total usable main memory size

freeram: c_ulong

Available memory size

sharedram: c_ulong

Amount of shared memory

bufferram: c_ulong

Memory used by buffers

totalswap: c_ulong

Total swap space size

freeswap: c_ulong

Swap space still available

procs: c_ushort

Number of current processes

pad: c_ushort

totalhigh: c_ulong

Total high memory size

freehigh: c_ulong

Available high memory size

mem_unit: c_uint

Memory unit size in bytes

f: [u8; 0]
