Enum Error 

#[non_exhaustive]
pub enum Error {
    Read {
        path: PathBuf,
        source: Error,
    },
    Parse {
        path: PathBuf,
        source: Error,
    },
    Generate {
        path: PathBuf,
        source: Error,
    },
    Write {
        path: PathBuf,
        source: Error,
    },
    OutDirNotSet,
}

Why generating bindings failed.

Messages name the file involved.

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.

Read

The IR file could not be read.

Fields

path: PathBuf

The IR file.

source: Error

The I/O error.

Parse

The IR file is not valid IR.

Fields

path: PathBuf

The IR file.

source: Error

Why it could not be parsed.

Generate

Bindings could not be generated from the IR files.

Fields

path: PathBuf

The first IR file; source names the build involved.

source: Error

Why generation failed.

Write

The bindings could not be written.

Fields

path: PathBuf

The file being written.

source: Error

The I/O error.

OutDirNotSet

Builder::generate was called outside a build script, where OUT_DIR is not set.

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, f: &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.
