Struct LeanPosition 

pub struct LeanPosition { /* private fields */ }

Source position attached to a Lean-emitted diagnostic.

line and column are 1-indexed (Lean convention). end_line / end_column are present when Lean attached an end position to the diagnostic — parser errors usually carry only a start position, while elaborator and kernel errors carry both.

Implementations

impl LeanPosition

pub fn line(&self) -> u32

1-indexed line number.

pub fn column(&self) -> u32

1-indexed column number.

pub fn end_line(&self) -> Option<u32>

1-indexed end line, if Lean attached one.

pub fn end_column(&self) -> Option<u32>

1-indexed end column, if Lean attached one.

Trait Implementations

impl Clone for LeanPosition

fn clone(&self) -> LeanPosition

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LeanPosition

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

Formats the value using the given formatter.

impl PartialEq for LeanPosition

fn eq(&self, other: &LeanPosition) -> 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<'lean> TryFromLean<'lean> for LeanPosition

fn try_from_lean(obj: Obj<'lean>) -> LeanResult<Self>

Decode obj into Self, returning a LeanError::Host with stage [HostStage::Conversion] if the object’s kind or payload is outside the type’s representable range.
