Struct CronExpression 

pub struct CronExpression { /* private fields */ }

A parsed two-field mini-cron expression "MINUTE HOUR".

See the module-level documentation for the supported syntax.

Implementations

impl CronExpression

pub fn parse(expr: &str) -> Result<Self, OrchestratorError>

Parse a cron expression string.

Errors

Returns OrchestratorError::ConfigError when the expression cannot be parsed.

Examples

use tokio_prompt_orchestrator::scheduler::CronExpression;

assert!(CronExpression::parse("*/5 *").is_ok());
assert!(CronExpression::parse("0 9").is_ok());
assert!(CronExpression::parse("invalid").is_err());

pub fn matches(&self, hour: u32, minute: u32) -> bool

Return true if this expression matches the given hour and minute.

Panics

This function does not panic.

pub fn as_str(&self) -> &str

Return the raw expression string as originally provided.

Panics

This function does not panic.

Trait Implementations

impl Clone for CronExpression

fn clone(&self) -> CronExpression

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CronExpression

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for CronExpression

fn deserialize<D: Deserializer<'de>>(d: D) -> Result<Self, D::Error>

Deserialize this value from the given Serde deserializer.

impl Display for CronExpression

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

Formats the value using the given formatter.

impl Eq for CronExpression

impl PartialEq for CronExpression

fn eq(&self, other: &CronExpression) -> 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 CronExpression

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

Serialize this value into the given Serde serializer.
