}

Various triggers that will cause the runtime to take snapshot of the WASM state and store it in the snapshot file.

Variants

Idle

Triggered when all the threads in the process goes idle

FirstListen

Triggered when a listen syscall is invoked on a socket for the first time

FirstEnviron

Triggered on reading the environment variables for the first time

FirstStdin

Triggered when the process reads stdin for the first time

FirstSigint

Issued on the first interrupt signal (Ctrl + C) the process receives, after that normal CTRL-C will apply.

PeriodicInterval

Triggered periodically based on a interval (default 10 seconds) which can be specified using the snapshot-interval option

Sigint

Issued if the user sends an interrupt signal (Ctrl + C).

Sigalrm

Alarm clock signal (used for timers)

Sigtstp

The SIGTSTP signal is sent to a process by its controlling terminal to request it to stop temporarily. It is commonly initiated by the user pressing Ctrl-Z.

Sigstop

The SIGSTOP signal instructs the operating system to stop a process for later resumption.

NonDeterministicCall

When a non-determinstic call is made

Bootstrap

Bootstrapping process

Transaction

Transaction

Explicit

Explicitly requested by the guest module

Converts to this type from the input type.

impl From<SnapshotTrigger> for JournalSnapshotTriggerV1

fn from(val: SnapshotTrigger) -> JournalSnapshotTriggerV1

fn from_str( s: &str, ) -> Result<SnapshotTrigger, <SnapshotTrigger as FromStr>::Err>

Parses a string s to return a value of this type.

impl Hash for SnapshotTrigger

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for SnapshotTrigger

fn cmp(&self, other: &SnapshotTrigger) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for SnapshotTrigger

fn eq(&self, other: &SnapshotTrigger) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for SnapshotTrigger

fn partial_cmp(&self, other: &SnapshotTrigger) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for SnapshotTrigger

fn serialize<S>( &self, serializer: S, ) -> Result<<S as Serializer>::Ok, <S as Serializer>::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.
