Struct Timestamp

pub struct Timestamp(pub DateTime<FixedOffset>);

A wrapper Timestamp type which allows conversion to Value::Timestamp for types using automatic conversion with serde::Serialize.

Examples

use cel_interpreter::{Context, Timestamp, Program};
use serde::Serialize;

#[derive(Serialize)]
struct MyStruct {
    ts: Timestamp,
}

let mut context = Context::default();

// MyStruct will be implicitly serialized into the CEL appropriate types
context
    .add_variable(
        "foo",
        MyStruct {
            ts: chrono::DateTime::parse_from_rfc3339("2025-01-01T00:00:00Z")
                .unwrap()
                .into(),
        },
    )
    .unwrap();

let program = Program::compile("foo.ts == timestamp('2025-01-01T00:00:00Z')").unwrap();
let value = program.execute(&context).unwrap();
assert_eq!(value, true.into());

Trait Implementations

impl Clone for Timestamp

fn clone(&self) -> Timestamp

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Timestamp

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

Formats the value using the given formatter.

impl Default for Timestamp

fn default() -> Timestamp

Returns the “default value” for a type.

impl From<DateTime<FixedOffset>> for Timestamp

fn from(value: DateTime<FixedOffset>) -> Self

Converts to this type from the input type.

impl From<Timestamp> for DateTime<FixedOffset>

fn from(value: Timestamp) -> Self

Converts to this type from the input type.

impl Hash for Timestamp

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for Timestamp

fn cmp(&self, other: &Timestamp) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Timestamp

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

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

const 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 PartialOrd for Timestamp

fn partial_cmp(&self, other: &Timestamp) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for Timestamp

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

where S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for Timestamp

impl Eq for Timestamp

impl StructuralPartialEq for Timestamp
