Enum ConflictPolicy 

pub enum ConflictPolicy {
    Fail,
    UseExisting,
    TerminateExisting,
}

Policy controlling what happens when [run()] is called with an instance_id that already has a persisted snapshot.

Variants

Fail

Return an error if the instance already exists (default).

UseExisting

Reuse the existing snapshot: return its current status without re-executing.

TerminateExisting

Terminate the existing instance (delete snapshot + clear signals) and start fresh.

Trait Implementations

impl Clone for ConflictPolicy

fn clone(&self) -> ConflictPolicy

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ConflictPolicy

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Default for ConflictPolicy

fn default() -> ConflictPolicy

Returns the “default value” for a type.

impl Display for ConflictPolicy

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl FromStr for ConflictPolicy

type Err = ParseError

The associated error which can be returned from parsing.

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

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

impl PartialEq for ConflictPolicy

fn eq(&self, other: &ConflictPolicy) -> 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 TryFrom<&str> for ConflictPolicy

type Error = ParseError

The type returned in the event of a conversion error.

fn try_from( s: &str, ) -> Result<ConflictPolicy, <ConflictPolicy as TryFrom<&str>>::Error>

Performs the conversion.
