Enum aws_sdk_sagemaker::model::ActionStatus

#[non_exhaustive]
pub enum ActionStatus {
    Completed,
    Failed,
    InProgress,
    Stopped,
    Stopping,
    UnknownValue,
    Unknown(UnknownVariantValue),
}

When writing a match expression against ActionStatus, it is important to ensure your code is forward-compatible. That is, if a match arm handles a case for a feature that is supported by the service but has not been represented as an enum variant in a current version of SDK, your code should continue to work when you upgrade SDK to a future version in which the enum does include a variant for that feature.

Here is an example of how you can make a match expression forward-compatible:

# let actionstatus = unimplemented!();
match actionstatus {
    ActionStatus::Completed => { /* ... */ },
    ActionStatus::Failed => { /* ... */ },
    ActionStatus::InProgress => { /* ... */ },
    ActionStatus::Stopped => { /* ... */ },
    ActionStatus::Stopping => { /* ... */ },
    ActionStatus::UnknownValue => { /* ... */ },
    other @ _ if other.as_str() == "NewFeature" => { /* handles a case for `NewFeature` */ },
    _ => { /* ... */ },
}

The above code demonstrates that when actionstatus represents NewFeature, the execution path will lead to the second last match arm, even though the enum does not contain a variant ActionStatus::NewFeature in the current version of SDK. The reason is that the variable other, created by the @ operator, is bound to ActionStatus::Unknown(UnknownVariantValue("NewFeature".to_owned())) and calling as_str on it yields "NewFeature". This match expression is forward-compatible when executed with a newer version of SDK where the variant ActionStatus::NewFeature is defined. Specifically, when actionstatus represents NewFeature, the execution path will hit the second last match arm as before by virtue of calling as_str on ActionStatus::NewFeature also yielding "NewFeature".

Explicitly matching on the Unknown variant should be avoided for two reasons:

• The inner data UnknownVariantValue is opaque, and no further information can be extracted.
• It might inadvertently shadow other intended match arms. Note: ActionStatus::Unknown has been renamed to ::UnknownValue.

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.

Completed

Failed

InProgress

Stopped

Stopping

UnknownValue

Note: ::Unknown has been renamed to ::UnknownValue.

Unknown(UnknownVariantValue)

Unknown contains new variants that have been added since this code was generated.

Implementations

fn as_ref(&self) -> &str

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for ActionStatus

fn clone(&self) -> ActionStatus

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ActionStatus

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

Formats the value using the given formatter.

impl From<&str> for ActionStatus

fn from(s: &str) -> Self

impl FromStr for ActionStatus

type Err = Infallible

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

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

impl Hash for ActionStatus

    H: Hasher,
    Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for ActionStatus

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

This method returns an Ordering between self and other.

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

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

This method tests greater than (for self and other) and is used by the > operator.

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