Enum CompileError 

pub enum CompileError {
    Lex {
        msg: String,
        span: Span,
    },
    Parse {
        msg: String,

    },
    Type {
        msg: String,
        span: Span,
    },
    Unsupported(String),
}

Any error produced while compiling rill-lang source.

Variants

Lex

The lexer hit a character it cannot start a token with.

Fields

msg: String

Human-readable cause.

span: Span

Location in source.

Parse

The parser encountered unexpected or missing tokens.

Fields

msg: String

Human-readable cause.

span: Span

Location in source.

Type

The type checker rejected the program (arity or scalar mismatch, etc.).

Fields

msg: String

Human-readable cause.

span: Span

Location in source.

Unsupported(String)

A well-typed program that the MVP backend cannot lower/run.

Trait Implementations

impl Clone for CompileError

fn clone(&self) -> CompileError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CompileError

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

Formats the value using the given formatter.

impl Display for CompileError

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

Formats the value using the given formatter.

impl Error for CompileError

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 CompileError

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