Struct CheckError 

pub struct CheckError {
    pub kind: CheckErrorKind,
    pub span: Span,
    pub expr_id: i64,
}

A type checking error.

Fields

kind: CheckErrorKind

The kind of error.

span: Span

The source span where the error occurred.

expr_id: i64

The expression ID where the error occurred.

Implementations

impl CheckError

pub fn new(kind: CheckErrorKind, span: Span, expr_id: i64) -> Self

Create a new check error.

pub fn undeclared_reference(name: &str, span: Span, expr_id: i64) -> Self

Create an undeclared reference error.

pub fn undeclared_reference_in( container: &str, name: &str, span: Span, expr_id: i64, ) -> Self

Create an undeclared reference error with container.

pub fn no_matching_overload( function: &str, arg_types: Vec<CelType>, span: Span, expr_id: i64, ) -> Self

Create a no matching overload error.

pub fn type_mismatch( expected: CelType, actual: CelType, span: Span, expr_id: i64, ) -> Self

Create a type mismatch error.

pub fn undefined_field( type_name: &str, field: &str, span: Span, expr_id: i64, ) -> Self

Create an undefined field error.

pub fn other(msg: impl Into<String>, span: Span, expr_id: i64) -> Self

Create an error with a custom message.

pub fn message(&self) -> String

Get the error message.

Trait Implementations

impl Clone for CheckError

fn clone(&self) -> CheckError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CheckError

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

Formats the value using the given formatter.

impl Display for CheckError

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

Formats the value using the given formatter.

impl Error for CheckError

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.
