Enum IrError 

pub enum IrError {
    DanglingReference {
        what: &'static str,
        id: u32,
    },
    Unsupported {
        message: String,
        span: Option<Span>,
    },
    Invalid {
        code: &'static str,
        message: String,
        span: Option<Span>,
    },
}

A structured IR error.

Variants

DanglingReference

A node reference is dangling or out of range.

Fields

what: &'static str

id: u32

Unsupported

A construct the IR does not support, with its source location.

Fields

message: String

span: Option<Span>

Invalid

A structural or invariant violation.

Fields

code: &'static str

message: String

span: Option<Span>

Implementations

impl IrError

pub fn code(&self) -> &'static str

Stable machine-readable code.

pub fn message(&self) -> String

Human-readable message.

pub fn span(&self) -> Option<Span>

The offending source span, when known.

Trait Implementations

impl Clone for IrError

fn clone(&self) -> IrError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for IrError

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

Formats the value using the given formatter.

impl Display for IrError

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

Formats the value using the given formatter.

impl Eq for IrError

impl Error for IrError

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 IrError

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

Equality operator ==.

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

Inequality operator !=.
