Enum ReadStatVarFormatClass 

#[non_exhaustive]
pub enum ReadStatVarFormatClass {
    Date,
    DateTime,
    DateTimeWithMilliseconds,
    DateTimeWithMicroseconds,
    DateTimeWithNanoseconds,
    Time,
    TimeWithMilliseconds,
    TimeWithMicroseconds,
    TimeWithNanoseconds,
}

Semantic classification of a SAS format string.

Determines the Arrow data type used for date/time/datetime variables:

Variant	Arrow Type
Date	Date32
DateTime	Timestamp(Second)
DateTimeWithMilliseconds	Timestamp(Millisecond)
DateTimeWithMicroseconds	Timestamp(Microsecond)
DateTimeWithNanoseconds	Timestamp(Nanosecond)
Time	Time32(Second)
TimeWithMilliseconds	Time32(Millisecond)
TimeWithMicroseconds	Time64(Microsecond)
TimeWithNanoseconds	Time64(Nanosecond)

This enum is #[non_exhaustive]: new precision levels or format classes may be added in minor releases.

Time range note

SAS TIME values are stored as seconds since midnight, but SAS treats them as durations and permits values that are negative or exceed 86 399 s (one day). Such values are written into the Arrow Time32/Time64 columns as-is, without clamping — so a column may legally hold a time-of-day outside the [0, 86400) range that consumers of Arrow time types might assume.

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.

Date

Date format (e.g. DATE9, MMDDYY10). Maps to Arrow Date32.

DateTime

DateTime format with second precision (e.g. DATETIME22).

DateTimeWithMilliseconds

DateTime format with millisecond precision (e.g. DATETIME22.3).

DateTimeWithMicroseconds

DateTime format with microsecond precision (e.g. DATETIME22.6).

DateTimeWithNanoseconds

DateTime format with nanosecond precision (e.g. DATETIME22.9).

Time

Time format with second precision (e.g. TIME8).

TimeWithMilliseconds

Time format with millisecond precision (e.g. TIME15.3).

TimeWithMicroseconds

Time format with microsecond precision (e.g. TIME15.6).

TimeWithNanoseconds

Time format with nanosecond precision (e.g. TIME15.9).

Trait Implementations

impl Clone for ReadStatVarFormatClass

fn clone(&self) -> ReadStatVarFormatClass

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ReadStatVarFormatClass

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

Formats the value using the given formatter.

impl PartialEq for ReadStatVarFormatClass

fn eq(&self, other: &ReadStatVarFormatClass) -> 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.

impl Serialize for ReadStatVarFormatClass

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
