Enum DeterministicMode 

pub enum DeterministicMode {
    Disabled {
        timezone: TimeZoneSpec,
    },
    Enabled {
        timestamp_utc: DateTime<Utc>,
        timezone: TimeZoneSpec,
    },
}

Deterministic evaluation configuration.

When enabled, volatile sources (clock/timezone) are derived solely from this config.

Variants

Disabled

Non-deterministic: uses the system clock.

Fields

timezone: TimeZoneSpec

Timezone used by volatile date/time builtins.

Enabled

Deterministic: uses a fixed timestamp in the provided timezone.

Fields

timestamp_utc: DateTime<Utc>

Fixed timestamp expressed in UTC.

timezone: TimeZoneSpec

Timezone used to interpret timestamp_utc for NOW()/TODAY().

Implementations

impl DeterministicMode

pub fn is_enabled(&self) -> bool

pub fn timezone(&self) -> &TimeZoneSpec

pub fn validate(&self) -> Result<(), ExcelError>

pub fn build_clock(&self) -> Result<Arc<dyn ClockProvider>, ExcelError>

Trait Implementations

impl Clone for DeterministicMode

fn clone(&self) -> DeterministicMode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DeterministicMode

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

Formats the value using the given formatter.

impl Default for DeterministicMode

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for DeterministicMode

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
