Enum aws_sdk_sagemaker::model::AssemblyType

#[non_exhaustive]
pub enum AssemblyType {
    Line,
    None,
    Unknown(UnknownVariantValue),
}

When writing a match expression against AssemblyType, 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 assemblytype = unimplemented!();
match assemblytype {
    AssemblyType::Line => { /* ... */ },
    AssemblyType::None => { /* ... */ },
    other @ _ if other.as_str() == "NewFeature" => { /* handles a case for `NewFeature` */ },
    _ => { /* ... */ },
}

The above code demonstrates that when assemblytype represents NewFeature, the execution path will lead to the second last match arm, even though the enum does not contain a variant AssemblyType::NewFeature in the current version of SDK. The reason is that the variable other, created by the @ operator, is bound to AssemblyType::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 AssemblyType::NewFeature is defined. Specifically, when assemblytype represents NewFeature, the execution path will hit the second last match arm as before by virtue of calling as_str on AssemblyType::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.

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.

Line

None

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 AssemblyType

fn clone(&self) -> AssemblyType

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for AssemblyType

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

Formats the value using the given formatter.

impl From<&str> for AssemblyType

fn from(s: &str) -> Self

impl FromStr for AssemblyType

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 AssemblyType

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 AssemblyType

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

This method returns an Ordering between self and other.

    Self: Sized,

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere
    Self: Sized + PartialOrd<Self>,

impl PartialEq<AssemblyType> for AssemblyType

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

This method tests for self and other values to be equal, and is used by ==.

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

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
