Struct PeplError 

pub struct PeplError {
    pub file: String,
    pub code: ErrorCode,
    pub severity: Severity,
    pub category: ErrorCategory,
    pub message: String,
    pub span: Span,
    pub source_line: String,
    pub suggestion: Option<String>,
}

A structured PEPL compiler error.

Matches the error message format defined in the spec (compiler.md). The View Layer renders these — it must not parse free-form strings.

Fields

file: String

Source file name.

code: ErrorCode

Error code (e.g., E201).

severity: Severity

Error severity.

category: ErrorCategory

Error category (derived from code).

message: String

Human-readable error message.

span: Span

Source location.

source_line: String

The exact source line for context.

suggestion: Option<String>

Optional fix suggestion (for LLM re-prompting).

Implementations

impl PeplError

pub fn new( file: impl Into<String>, code: ErrorCode, message: impl Into<String>, span: Span, source_line: impl Into<String>, ) -> Self

Create a new error.

pub fn with_suggestion(self, suggestion: impl Into<String>) -> Self

Attach a fix suggestion.

Trait Implementations

impl Clone for PeplError

fn clone(&self) -> PeplError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PeplError

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for PeplError

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for PeplError

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

Formats the value using the given formatter.

impl Error for PeplError

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 Serialize for PeplError

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
