Enum Error 

pub enum Error {
    Io(Error),
    DuplicatePath {
        path: String,
    },
    Protox(Box<Error>),
    DescriptorPool(DescriptorError),
    Tonic(Box<dyn Error + Send + Sync>),
}

Errors surfaced by the proto-build-kit primitives.

Variants

Io(Error)

I/O failure (tempdir creation, file write, parent-dir mkdir).

DuplicatePath

Stager::stage() detected two entries writing to the same protoc-relative path.

Fields

path: String

The relative path declared twice.

Protox(Box<Error>)

protox failed to parse one of the .proto files.

DescriptorPool(DescriptorError)

prost-reflect descriptor-pool construction failed.

Tonic(Box<dyn Error + Send + Sync>)

tonic-prost-build codegen failed (only surfaced when the tonic feature is enabled).

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, __formatter: &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.

impl From<DescriptorError> for Error

fn from(source: DescriptorError) -> Self

Converts to this type from the input type.

impl From<Error> for Error

fn from(source: Error) -> Self

impl From<Error> for Error

fn from(e: Error) -> Self
