Struct OutputConversionError

pub struct OutputConversionError { /* private fields */ }

An error produced when attempting to convert Command Output to a custom format (such as Utf8Output).

Produced by methods like CommandExt::output_checked_with and CommandExt::output_checked_utf8.

let mut command = Command::new("sh");
command.args(["-c", "echo puppy doggy"]);
let displayed: Utf8ProgramAndArgs = (&command).into();
let mut output = command.output().unwrap();
output.stdout[5] = 0xc0; // Invalid UTF-8 byte.
let inner: Result<utf8_command::Utf8Output, _> = output.try_into();
let error = OutputConversionError::new(
    Box::new(displayed),
    Box::new(inner.unwrap_err())
);
assert_eq!(
    error.to_string(),
    "Failed to convert `sh` output: \
    Stdout contained invalid utf-8 sequence of 1 bytes from index 5: \
    \"puppy�doggy\\n\""
);

Implementations

impl OutputConversionError

pub fn new( command: Box<dyn CommandDisplay + Send + Sync>, inner: Box<dyn Display + Send + Sync>, ) -> Self

Construct a new OutputConversionError.

Trait Implementations

impl Debug for OutputConversionError

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

Formats the value using the given formatter.

impl Display for OutputConversionError

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

impl Error for OutputConversionError

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<OutputConversionError> for Error

fn from(error: OutputConversionError) -> Self

Converts to this type from the input type.
