Struct TermInfoNode 

pub struct TermInfoNode {
    pub start_line: u32,
    pub start_column: u32,
    pub end_line: u32,
    pub end_column: u32,
    pub expr_str: String,
    pub type_str: String,
    pub expected_type_str: Option<String>,
}

One Lean.Elab.TermInfo projection.

expr_str / type_str use Lean’s raw Expr.toString projection (same shape as crate::LeanSession::expr_to_string_raw); for the notation-aware rendering call the optional crate::host::meta::pp_expr service against the original Expr.

Fields

start_line: u32

1-based start line.

start_column: u32

1-based start column.

end_line: u32

1-based end line.

end_column: u32

1-based end column.

expr_str: String

Expr.toString of the elaborated expression.

type_str: String

Expr.toString of the inferred type, or empty if inference failed at the recorded site.

expected_type_str: Option<String>

Expr.toString of the expected type when the elaborator recorded one (e.g., a coercion site).

Trait Implementations

impl Clone for TermInfoNode

fn clone(&self) -> TermInfoNode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TermInfoNode

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

Formats the value using the given formatter.

impl PartialEq for TermInfoNode

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

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.
