Struct AttemptView 

pub struct AttemptView {

    pub n: Option<u64>,
    pub chain_index: Option<u32>,
    pub channel: Option<String>,
    pub action_name: Option<String>,
    pub call_id: String,
    pub outcome: Option<String>,
    pub error_class: Option<String>,
    pub execution_mode: Option<String>,
    pub fallback_reason: Option<String>,
    pub error: Option<ErrorInfo>,
    pub args_snapshot: Value,
    pub started_at_ms: Option<u64>,
    pub finished_at_ms: Option<u64>,
    pub intent_seq: u64,
    pub settled_seq: Option<u64>,
    pub evidence: Vec<AssetRef>,
}

One attempt, enriched beyond the checkpoint’s discriminant-only AttemptRecord by joining the actionIntent/actionSettled events (07 §2.2: dossier attempts carry the ErrorInfo verbatim + timing).

Fields

n: Option<u64>

Attempt ordinal from the intent path (#n), when recorded.

chain_index: Option<u32>

1-based binding.attempts chain position (item ②, 2026-07-18); absent on pre-incorporation ledgers.

channel: Option<String>

The dispatched attempt’s locating channel (wire literal).

action_name: Option<String>

The dispatched attempt’s provider-native action name.

call_id: String

The dispatch correlation id (WAL pairing key).

outcome: Option<String>

Terminal discriminant (succeeded/failed/cancelled/timedOut); absent while the attempt is still in the crash window.

error_class: Option<String>

Closed taxonomy class, as the runner recorded it.

execution_mode: Option<String>

Execution mode the daemon reported.

fallback_reason: Option<String>

Daemon-side degradation reason, when any.

error: Option<ErrorInfo>

Full provider error on non-success terminals (verbatim).

args_snapshot: Value

Dispatch argument snapshot (from the WAL intent).

started_at_ms: Option<u64>

Provider-reported start, on success.

finished_at_ms: Option<u64>

Provider-reported finish, on success.

intent_seq: u64

Ledger seq of the intent.

settled_seq: Option<u64>

Ledger seq of the terminal, once settled.

evidence: Vec<AssetRef>

Declared settlement evidence, verbatim from the terminal’s result.evidence (item ③ — the provenance join key; the LOCALIZED copies live on the dossier’s evidence gallery).

Trait Implementations

impl Clone for AttemptView

fn clone(&self) -> AttemptView

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AttemptView

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for AttemptView

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

where __D: Deserializer<'de>,

impl JsonSchema for AttemptView

fn schema_name() -> Cow<'static, str>

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn inline_schema() -> bool
