Struct AdaptivePinKey 

pub struct AdaptivePinKey {
    pub error_signature: String,
    pub operation: String,
}

Pin key = (error_signature, operation) per Q6 of the 2026-04-20 spec amendment.

error_signature is <error_type>:<short_hash_of_structural_props>. Structural properties — not exact values — drive the hash so ConnectionTimeout{after: 30s} and ConnectionTimeout{after: 45s} share a signature, while ConnectionTimeout and ConnectionRefused pin independently.

Fields

error_signature: String

<type_name>:<hash> identifier.

operation: String

Operation name, e.g., "Network.fetch_payment_status".

Implementations

impl AdaptivePinKey

pub fn from_error_and_op(error: &dyn ErrorValue, operation: &str) -> Self

Builds a pin key from the error and operation name.

pub fn decision_id(&self) -> String

SHA-256 content hash of (operation, error_signature); used as the Decision::id so a pin can be replayed.

Trait Implementations

impl Clone for AdaptivePinKey

fn clone(&self) -> AdaptivePinKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AdaptivePinKey

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

Formats the value using the given formatter.

impl Hash for AdaptivePinKey

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 AdaptivePinKey

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