Struct Error 

pub struct Error {
    pub message: String,
    pub line: usize,
    pub col: usize,
    /* private fields */
}

A compilation error, carrying a human-readable message and a 1-based source position (line/col are 0 when the position is unknown).

Implements std::error::Error, so it composes with ? and the wider error ecosystem.

For byte-exact dart-sass diagnostics the evaluator attaches a span length (in source bytes) and a rendered snippet block at the AST-node boundary. When rendered is present, [Display] emits it verbatim (the full Error: … + source-span snippet + stack trace); otherwise it falls back to the legacy Error: <msg> (line:col) one-liner.

Fields

message: String

Human-readable description of what went wrong.

line: usize

1-based line number, or 0 if unknown.

col: usize

1-based column number, or 0 if unknown.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Eq for Error

impl Error for Error

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 Error

fn eq(&self, other: &Error) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
