Code generation error.

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.

MissingField(&'static str)

A required field was absent in a descriptor.

The &'static str names the missing field for diagnostics.

InvalidTypePath(String)

A resolved type path string could not be parsed as a Rust type.

InvalidSyntax(String)

The accumulated TokenStream failed to parse as valid Rust syntax.

FileNotFound(String)

A requested file was not present in the descriptor set.

Other(String)

Unexpected descriptor state (e.g. a map entry or oneof that cannot be resolved to a known descriptor field).

ReservedFieldName

A proto field name uses the __buffa_ reserved prefix, which would conflict with buffa’s internal generated fields.

Fields

message_name: String

field_name: String

ModuleNameConflict

Two sibling messages produce the same Rust module name after snake_case conversion (e.g., HTTPRequest and HttpRequest both become pub mod http_request).

Fields

scope: String

name_a: String

name_b: String

module_name: String

NestedTypeOneofConflict

A nested message/enum name collides with a oneof enum name inside the same message module.

Fields

scope: String

nested_name: String

oneof_name: String

rust_name: String

ViewNameConflict

A message named FooView collides with the generated view type for message Foo.

Fields

scope: String

owned_msg: String

view_msg: String

Trait Implementations

impl Clone for CodeGenError

fn clone(&self) -> CodeGenError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

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.
