Header attached to every log message.

Provides standard identifying information about a log in order to assist in decoding as well as filtering (log level).

Fields

level: c_uchar

alias for {LogLevel}

reason: c_uchar

alias for {LogReason}

type_: c_ushort

alias for {EventType}

pid: c_ulong

process id that is triggering the hook

tid: c_ulong

thread id that is triggering the hook

uid: c_ulong

effective user id of the process

pol_id: c_ulong

policy id for this object

comm: [c_uchar; 16]

same as /proc/{pid}/comm

Implementations

impl log_hdr

pub fn level(&self) -> LogLevel

Parse the type_ field from the generated C binding of struct log_hdr into a variant of the LogLevel enum derived from logging_types.h using strum.

Defaults to LOG_LEVEL_OFF.

pub fn type_(&self) -> EventType

Parse the type_ field from the generated C binding of struct log_hdr into a variant of the EventType enum derived from logging_types.h using strum.

Defaults to LOG_REASON_UNKNOWN
