Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Empty

Record does not contain valid info

RunLevel

Change in system run-level (see init(8))

Fields of RunLevel

kernel_version: String

Kernel version

time: DateTime<Utc>

Time entry was made

BootTime(DateTime<Utc>)

Time of system boot

NewTime(DateTime<Utc>)

Time after system clock change

OldTime(DateTime<Utc>)

Time before system clock change

InitProcess

Process spawned by init(8)

Fields of InitProcess

pid: pid_t

PID of the init process

time: DateTime<Utc>

Time entry was made

LoginProcess

Session leader process for user login

Fields of LoginProcess

pid: pid_t

PID of the login process

time: DateTime<Utc>

Time entry was made

UserProcess

Normal process

Fields of UserProcess

pid: pid_t

PID of login process

line: String

Device name of tty

user: String

Username

host: String

Hostname for remote login

session: pid_t

Session ID (getsid(2))

time: DateTime<Utc>

Time entry was made

DeadProcess

Terminated process

Fields of DeadProcess

pid: pid_t

PID of the terminated process

Accounting

Not implemented

Non-exhaustive enum variants could have additional fields added in future. Therefore, non-exhaustive enum variants cannot be constructed in external crates and cannot be matched against.
