Enum ColumnNameCharacterMap 

#[non_exhaustive]
pub enum ColumnNameCharacterMap {
    Unspecified,
    Strict,
    V1,
    V2,
    UnknownValue(UnknownValue),
}

Indicates the character map used for column names.

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

Unspecified column name character map.

Strict

Support flexible column name and reject invalid column names.

V1

Support alphanumeric + underscore characters and names must start with a letter or underscore. Invalid column names will be normalized.

V2

Support flexible column name. Invalid column names will be normalized.

UnknownValue(UnknownValue)

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

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

Implementations

impl ColumnNameCharacterMap

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.
