Struct EmbassyInstant 

pub struct EmbassyInstant(/* private fields */);

Available on crate feature embassy-time only.

A PkInstant adapter for embassy_time::Instant.

This type bridges the PK Command timing abstraction with the embassy-time crate, enabling timeout handling in no_std/embedded environments that use Embassy.

Availability

Enabled when the embassy feature is active (it also enables embassy-time).

Why this wrapper exists

embassy_time::Instant is tied to embassy_time::Duration, while PK Command uses core::time::Duration. These durations can be converted, but their types are not directly compatible with the PkCommand signature, so a newtype adapter keeps the API consistent without large generic changes.

Notes

• Implements Add<Duration> with millisecond precision.
• elapsed() guards against clock rollback by returning 0 if the current instant is earlier than the stored instant.

Example

use pk_command::{
    EmbassyInstant, PkCommand, PkCommandConfig, PkHashmapMethod, PkHashmapVariable,
};

// embassy_timer::Instant must be constructed within an Embassy context
// otherwise the code would not compile.
#[embassy_executor::task]
async fn example() {
    let pk = PkCommand::<_, _, EmbassyInstant>::new(
        PkCommandConfig::default(64),
        PkHashmapVariable::new(vec![]),
        PkHashmapMethod::new(vec![]),
    );
}

Trait Implementations

impl Add<Duration> for EmbassyInstant

type Output = EmbassyInstant

The resulting type after applying the + operator.

fn add(self, rhs: Duration) -> Self::Output

Performs the + operation.

impl Clone for EmbassyInstant

fn clone(&self) -> EmbassyInstant

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl From<Instant> for EmbassyInstant

fn from(inst: Instant) -> Self

Converts to this type from the input type.

impl Ord for EmbassyInstant

fn cmp(&self, other: &EmbassyInstant) -> 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,

impl PartialEq for EmbassyInstant

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

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 PkInstant for EmbassyInstant

fn now() -> Self

Returns the current instant.

fn elapsed(&self) -> Duration

Returns the duration elapsed since this instant.
