Errors returned by Generator::generate when the configuration is invalid for the given schema.

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.

HeaderValueOutOfRange

A schema value cannot be represented by its declared message-header field without using a reserved/null value.

Fields

field: String

Header field name.

value: u64

Schema value that would be written.

maximum: u64

Maximum value declared by the field encoding.

context: String

Schema or message that supplied the value.

InvalidConversion

A conversion selector matched no fields, or a domain type path is invalid.

Fields

selector: String

Description of the selector.

reason: String

Why validation failed.

ConversionCollision

Two selectors mapped to the same generated method name.

Fields

method: String

The colliding method name.

selector_a: String

The first selector that produced the collision.

selector_b: String

The second selector that produced the collision.

InvalidGeneratedSource

Generated module source failed its own syntax check. This is always an ergo-sbe codegen bug — report it.

Fields

module: String

Which module produced invalid Rust.

error: String

The syn parse error.

InvalidConfiguration

A GenerationConfig field was rejected by codegen validation.

Fields

option: String

Which config option was rejected.

value: String

The rejected value.

reason: String

Why it was rejected.

IncompatibleSharedType

Multi-schema generation found the same type name with incompatible wire layouts across schemas.

Fields

name: String

Shared type name (enum, set, or composite).

owner_module: String

Module that first defined the type.

consumer_module: String

Module that reuses the name with a different layout.

difference: String

First differing property / fingerprint mismatch summary.

Trait Implementations

impl Clone for GenerateError

fn clone(&self) -> GenerateError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GenerateError

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

Formats the value using the given formatter.

impl Display for GenerateError

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

Formats the value using the given formatter.

impl Eq for GenerateError

impl Error for GenerateError

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 From<GenerateError> for BuildError

fn from(source: GenerateError) -> Self

Converts to this type from the input type.

impl PartialEq for GenerateError

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

Equality operator ==.

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

Inequality operator !=.
