Struct CronSchedule 

pub struct CronSchedule { /* private fields */ }

A validated cron expression.

Internally wraps a croner::Cron, guaranteeing that the expression has been parsed and validated at construction time.

as_str returns the original expression as provided by the user, not the normalized form.

Examples

use ironflow_engine::schedule::CronSchedule;

let sched = CronSchedule::new("0 0 * * * *").unwrap();
assert_eq!(sched.as_str(), "0 0 * * * *");

let bad = CronSchedule::new("not a cron");
assert!(bad.is_err());

Implementations

impl CronSchedule

pub fn new(expression: &str) -> Result<Self, String>

Parse and validate a cron expression.

Accepts 5-field (standard) or 6-field (with seconds) expressions, as supported by croner.

Errors

Returns an error string if the expression is syntactically invalid.

Examples

use ironflow_engine::schedule::CronSchedule;

assert!(CronSchedule::new("0 */5 * * * *").is_ok());
assert!(CronSchedule::new("garbage").is_err());

pub fn as_str(&self) -> &str

Returns the original cron expression string as provided to new.

Trait Implementations

impl Clone for CronSchedule

fn clone(&self) -> CronSchedule

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CronSchedule

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for CronSchedule

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for CronSchedule

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

Formats the value using the given formatter.

impl PartialEq for CronSchedule

fn eq(&self, other: &Self) -> 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 CronSchedule

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.
