Enum LeanWorkerProofPositionSelector 

#[non_exhaustive]
pub enum LeanWorkerProofPositionSelector {
    Default,
    Index {
        index: u32,
    },
    AfterText {
        text: String,
        occurrence: Option<u32>,
    },
    Entry,
}

Intent selector for one proof position inside a declaration.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Default

Select the first tactic state in declaration order — the point after the first tactic has run. A try_proof_step candidate is spliced after that tactic, so a from-scratch tactic block does not elaborate against the pristine entry goal; use Entry for that.

Index

Select the index-th tactic state in declaration order — the point after the index-th tactic has run.

Fields

index: u32

AfterText

Select the tactic whose source text exactly matches text.

Fields

text: String

occurrence: Option<u32>

Entry

Select the goal state before any tactic runs — the pristine entry goal of the declaration’s proof. A try_proof_step candidate is spliced before the first tactic, so a from-scratch tactic block elaborates against this goal (the one proof_state reports as goals_before of the first position). Anchors on the first enumerated tactic’s pre-state, so the declaration must have at least one elaborated tactic.
