Enum WriteStreamView 

#[non_exhaustive]
pub enum WriteStreamView {
    Unspecified,
    Basic,
    Full,
    UnknownValue(UnknownValue),
}

WriteStreamView is a view enum that controls what details about a write stream should be returned.

Working with unknown values

This enum is defined as #[non_exhaustive] because Google Cloud may add additional enum variants at any time. Adding new variants is not considered a breaking change. Applications should write their code in anticipation of:

• New values appearing in future releases of the client library, and
• New values received dynamically, without application changes.

Please consult the Working with enums section in the user guide for some guidelines.

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.

Unspecified

The default / unset value.

Basic

The BASIC projection returns basic metadata about a write stream. The basic view does not include schema information. This is the default view returned by GetWriteStream.

Full

The FULL projection returns all available write stream metadata, including the schema. CreateWriteStream returns the full projection of write stream metadata.

UnknownValue(UnknownValue)

If set, the enum was initialized with an unknown value.

Applications can examine the value using WriteStreamView::value or WriteStreamView::name.

Implementations

impl WriteStreamView

pub fn value(&self) -> Option<i32>

Gets the enum value.

Returns None if the enum contains an unknown value deserialized from the string representation of enums.

pub fn name(&self) -> Option<&str>

Gets the enum value as a string.

Returns None if the enum contains an unknown value deserialized from the integer representation of enums.
