Errors that can occur during code generation

Each error variant provides detailed context about what went wrong during the code generation process.

Variants

RenderError

Failed to render a specific part of the code

This typically indicates a bug in the generator logic.

Fields

component: String

The component that failed to render (e.g., “struct”, “field”, “enum”)

context: String

Context where the error occurred (e.g., “User”, “Address”)

message: String

Description of what went wrong

FormatError

String formatting error

This occurs when writing to the output buffer fails.

Fields

context: String

Context where formatting failed

source: Error

The underlying fmt::Error

ValidationError

Module validation failed

The IR module contains invalid data that cannot be generated.

Fields

reason: String

Reason why validation failed

suggestion: Option<String>

Optional suggestion for fixing the issue

InvalidIdentifier

Empty or invalid identifier name

Fields

name: String

The invalid identifier name

context: String

Context where the identifier is used (e.g., “struct name”, “field name”)

reason: String

Reason why it’s invalid

UnsupportedType

Unsupported type encountered

Fields

type_name: String

The type that is not supported

context: String

Context where the type was encountered

reason: String

Why it’s not supported

alternative: Option<String>

Optional alternative or workaround

MaxDepthExceeded

Maximum recursion depth exceeded

Prevents stack overflow from deeply nested types.

Fields

context: String

Context where max depth was reached

max_depth: usize

The maximum allowed depth

Implementations

impl CodegenError

pub fn with_suggestion(self, suggestion: impl Into<String>) -> Self

Add a suggestion to an error

Trait Implementations

impl Debug for CodegenError

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

Formats the value using the given formatter.

impl Display for CodegenError

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

Formats the value using the given formatter.

impl Error for CodegenError

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<Error> for CodegenError

fn from(err: Error) -> Self

Converts to this type from the input type.
