Fields

location: AnyEntity

[−] Expand description

The entity causing the verifier error.

context: Option<String>

[−] Expand description

Optionally provide some context for the given location; e.g., for inst42 provide Some("v3 = iconst.i32 0") for more comprehensible errors.

message: String

[−] Expand description

impl Eq for VerifierError

impl Error for VerifierError[+]

[+] Show hidden undocumented items

pub fn source(&self) -> Option<&(dyn Error + 'static)>[−]

The lower-level source of this error, if any.

pub fn backtrace(&self) -> Option<&Backtrace>[−]

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

pub fn description(&self) -> &str[−]

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

pub fn cause(&self) -> Option<&dyn Error>

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

impl<L, C, M> From<(L, C, M)> for VerifierError where
    L: Into<AnyEntity>,
    C: Into<String>,
    M: Into<String>, [+]

Convenience converter for making error-reporting less verbose.

Converts a tuple of (location, context, message) to a VerifierError.

use cranelift_codegen::verifier::VerifierErrors;
use cranelift_codegen::ir::Inst;
let mut errors = VerifierErrors::new();
errors.report((Inst::from_u32(42), "v3 = iadd v1, v2", "iadd cannot be used with values of this type"));
// note the double parenthenses to use this syntax

[+] Show hidden undocumented items

fn from(items: (L, C, M)) -> Self[−]

Performs the conversion.

impl<L, M> From<(L, M)> for VerifierError where
    L: Into<AnyEntity>,
    M: Into<String>, [+]

Convenience converter for making error-reporting less verbose.

Same as above but without context.

fn from(items: (L, M)) -> Self[−]

Performs the conversion.

impl PartialEq<VerifierError> for VerifierError[+]

[+] Show hidden undocumented items

fn eq(&self, other: &VerifierError) -> bool[−]

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &VerifierError) -> bool[−]

This method tests for !=.
