Struct StateId 

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

Enforced: “<machine_id>.<step_id>.<state_local_id>”

Implementations

impl StateId

pub fn new(value: impl Into<String>) -> Result<Self, IdValidationError>

Creates a state identifier after validating the <machine>.<step>.<state> shape.

Each segment must satisfy the same naming contract as OpId.

Examples

use mfm_machine::ids::StateId;

let state_id = StateId::new("portfolio_snapshot.fetch_balances.read_eth")?;
assert_eq!(state_id.as_str(), "portfolio_snapshot.fetch_balances.read_eth");

pub fn must_new(value: impl Into<String>) -> Self

Creates a StateId and panics if the value is invalid.

pub fn as_str(&self) -> &str

Returns the validated identifier as a borrowed string slice.

Trait Implementations

impl Clone for StateId

fn clone(&self) -> StateId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StateId

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for StateId

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for StateId

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

Formats the value using the given formatter.

impl From<StateId> for String

fn from(value: StateId) -> Self

Converts to this type from the input type.

impl Hash for StateId

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 PartialEq for StateId

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

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<&str> for StateId

type Error = IdValidationError

The type returned in the event of a conversion error.

fn try_from(value: &str) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<String> for StateId

type Error = IdValidationError

The type returned in the event of a conversion error.

fn try_from(value: String) -> Result<Self, Self::Error>

Performs the conversion.
