Why Generator::generate failed.

Messages name the module, item or build involved.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

InvalidIr(ValidationErrors)

The IR failed validation.

ModuleNameClash

Two IR modules would get the same Rust module name.

Fields

first: String

The first IR module with that name.

second: String

The second IR module with that name.

rust_name: String

The Rust module name both would get.

UnknownModule

Generator::module_name or Generator::accept_build names a module that isn’t in the IR.

Fields

option: &'static str

The option that named it: "module_name" or "accept_build".

name: String

The IR module name given.

InvalidModuleName

Generator::module_name was given a name that isn’t a valid Rust module name.

Fields

name: String

The Rust module name given.

DuplicateBuild

Two builds have the same label, or labels that make the same Build variant.

Fields

label: String

The second build’s label.

InvalidBuildLabel

A build’s label isn’t lowercase letters, digits and single underscores, starting with a letter.

Fields

label: String

The label given.

UnknownBuild

Generator::accept_build names a build label no IR has.

Fields

label: String

The label given.

BuildsDiffer(Box<BuildsDiffer>)

Two builds’ IRs disagree on a type, a function’s signature or a global’s type, so one set of bindings can’t fit both.

Trait Implementations

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 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.
