Enum Error 

#[non_exhaustive]
pub enum Error {
    NoStdin,
    NoStdout,
    InvalidUtf8(FromUtf8Error),
    BrokenStdin(BrokenStdinError),
    BrokenStdout(BrokenStdoutError),
    Decode(DecoderError),
    Child(String),
}

Error variants for custom providers.

These are returned to the application as ProviderError::ApplicationError variant and can be accessed with anyhows downcast_* functions.

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.

NoStdin

failed to capture stdin of spawned child process

NoStdout

failed to capture stdout of spawned child process

InvalidUtf8(FromUtf8Error)

failed to parse command output into string

BrokenStdin(BrokenStdinError)

failed to write message to child process

BrokenStdout(BrokenStdoutError)

failed to read message from child process

Decode(DecoderError)

failed to decode message from custom provider

Child(String)

unexpected error from custom provider

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.
