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.

Trait Implementations

impl Clone for LeanWorkerProofPositionSelector

fn clone(&self) -> LeanWorkerProofPositionSelector

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LeanWorkerProofPositionSelector

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

Formats the value using the given formatter.

impl Default for LeanWorkerProofPositionSelector

fn default() -> LeanWorkerProofPositionSelector

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for LeanWorkerProofPositionSelector

fn deserialize<__D>( __deserializer: __D, ) -> Result<LeanWorkerProofPositionSelector, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for LeanWorkerProofPositionSelector

impl PartialEq for LeanWorkerProofPositionSelector

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
