Enum RenderError 

pub enum RenderError {
    UnknownSymbol {
        id: SymbolId,
        context: &'static str,
    },
    NotAMemory,
}

Errors produced by LispRenderer::render_memory. None of these are fatal for the caller — the renderer can skip unrenderable records and continue.

Variants

UnknownSymbol

A SymbolId referenced by a record is not allocated in the supplied symbol table. For a well-formed committed log this cannot happen (log replay populates the table); in a corrupted log this surfaces the dangling reference.

Fields

id: SymbolId

The offending ID.

context: &'static str

Human-readable slot name (for diagnostics).

NotAMemory

The record’s opcode is not a memory record (Sem / Epi / Pro / Inf) — these shapes do not have a write-surface Lisp form. The caller should continue past the record.

Trait Implementations

impl Debug for RenderError

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

Formats the value using the given formatter.

impl Display for RenderError

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

Formats the value using the given formatter.

impl Error for RenderError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl PartialEq for RenderError

fn eq(&self, other: &RenderError) -> 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.
