Struct CrontabSpec 

#[non_exhaustive]
pub struct CrontabSpec {
    pub text: String,
    pub time_zone: String,
    pub creation_window: Option<Duration>,
    /* private fields */
}

CrontabSpec can be used to specify the version time and frequency at which the backup should be created.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

text: String

Required. Textual representation of the crontab. User can customize the backup frequency and the backup version time using the cron expression. The version time must be in UTC timezone.

The backup will contain an externally consistent copy of the database at the version time. Allowed frequencies are 12 hour, 1 day, 1 week and 1 month. Examples of valid cron specifications:

• 0 2/12 * * * : every 12 hours at (2, 14) hours past midnight in UTC.
• 0 2,14 * * * : every 12 hours at (2,14) hours past midnight in UTC.
• 0 2 * * * : once a day at 2 past midnight in UTC.
• 0 2 * * 0 : once a week every Sunday at 2 past midnight in UTC.
• 0 2 8 * * : once a month on 8th day at 2 past midnight in UTC.

time_zone: String

Output only. The time zone of the times in CrontabSpec.text. Currently only UTC is supported.

creation_window: Option<Duration>

Output only. Schedule backups will contain an externally consistent copy of the database at the version time specified in schedule_spec.cron_spec. However, Spanner may not initiate the creation of the scheduled backups at that version time. Spanner will initiate the creation of scheduled backups within the time window bounded by the version_time specified in schedule_spec.cron_spec and version_time + creation_window.

Implementations

impl CrontabSpec

pub fn new() -> Self

pub fn set_text<T: Into<String>>(self, v: T) -> Self

Sets the value of text.

pub fn set_time_zone<T: Into<String>>(self, v: T) -> Self

Sets the value of time_zone.

pub fn set_creation_window<T>(self, v: T) -> Self

where T: Into<Duration>,

Sets the value of creation_window.

pub fn set_or_clear_creation_window<T>(self, v: Option<T>) -> Self

where T: Into<Duration>,

Sets or clears the value of creation_window.

Trait Implementations

impl Clone for CrontabSpec

fn clone(&self) -> CrontabSpec

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CrontabSpec

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

Formats the value using the given formatter.

impl Default for CrontabSpec

fn default() -> CrontabSpec

Returns the “default value” for a type.

impl Message for CrontabSpec

fn typename() -> &'static str

The typename of this message.

impl PartialEq for CrontabSpec

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