Enum BuildError 

pub enum BuildError {
    Parse {
        file: String,
        line: u32,
        col: u32,
        message: String,
    },
    Codegen {
        message: String,
    },
    Io(Error),
}

Rich error type for .proto compilation operations.

Carries structured location information where available so that IDEs and build-script consumers can point the user directly to the offending source position.

Variants

Parse

A .proto file has a syntax error with location information.

Fields

file: String

Path to the file containing the error (empty when not available).

line: u32

1-indexed line number (0 when not available).

col: u32

1-indexed column number (0 when not available).

message: String

Human-readable error message.

Codegen

Code generation failed.

Fields

message: String

Human-readable description of what went wrong.

Io(Error)

An I/O error occurred (e.g. reading a .proto file or writing output).

Trait Implementations

impl Debug for BuildError

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

Formats the value using the given formatter.

impl Display for BuildError

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

Formats the value using the given formatter.

impl Error for BuildError

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.
