Enum LangSpecError 

pub enum LangSpecError {
    Source(SourceError),
    Lex(LexerError),
    Parse {
        code: CompilerErrorCode,
        message: String,
    },
}

Errors returned while bootstrapping the builtin language spec.

Variants

Source(SourceError)

Source loading failure.

Lex(LexerError)

Lexing failure.

Parse

The language specification text was malformed.

Fields

code: CompilerErrorCode

Upstream-aligned compiler error code.

message: String

Human-readable message.

Trait Implementations

impl Debug for LangSpecError

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

Formats the value using the given formatter.

impl Display for LangSpecError

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

Formats the value using the given formatter.

impl Error for LangSpecError

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.
