Enum RoundingMode 

#[non_exhaustive]
pub enum RoundingMode {
    Unspecified,
    RoundHalfAwayFromZero,
    RoundHalfEven,
    UnknownValue(UnknownValue),
}

Rounding mode options that can be used when storing NUMERIC or BIGNUMERIC values.

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 will default to using ROUND_HALF_AWAY_FROM_ZERO.

RoundHalfAwayFromZero

ROUND_HALF_AWAY_FROM_ZERO rounds half values away from zero when applying precision and scale upon writing of NUMERIC and BIGNUMERIC values. For Scale: 0 1.1, 1.2, 1.3, 1.4 => 1 1.5, 1.6, 1.7, 1.8, 1.9 => 2

RoundHalfEven

ROUND_HALF_EVEN rounds half values to the nearest even value when applying precision and scale upon writing of NUMERIC and BIGNUMERIC values. For Scale: 0 1.1, 1.2, 1.3, 1.4 => 1 1.5 => 2 1.6, 1.7, 1.8, 1.9 => 2 2.5 => 2

UnknownValue(UnknownValue)

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

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

Implementations

impl RoundingMode

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.
