Enum CodegenError 

#[non_exhaustive]
pub enum CodegenError {
    Protoc(String),
    DescriptorIo(Error),
    DescriptorDecode(String),
    Buffa(String),
    OptionDecode {
        path: String,
        detail: String,
    },
    OutputIo(Error),
}

Errors returned by the option scanner.

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.

Protoc(String)

The protoc invocation failed.

DescriptorIo(Error)

The descriptor set could not be read.

DescriptorDecode(String)

The descriptor set could not be decoded.

Buffa(String)

The buffa-build invocation failed.

OptionDecode

The custom option bytes could not be decoded.

Fields

path: String

Fully qualified message/field path.

detail: String

Human-readable detail.

OutputIo(Error)

IO error while writing generated files.

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.
