Enum Error

pub enum Error {
    InvalidCommand {
        command_name: String,
    },
    TooManyParameters {
        command: &'static str,
    },
    UnexpectedCommand {
        command: &'static str,
    },
    ChildFailed {
        status: ExitStatus,
    },
    PipeFailed,
    IoError(Error),
    FromUtf8Error(FromUtf8Error),
    FileError {
        filename: String,
        line: usize,
        error: Box<Error>,
    },
}

Error enum for parsing errors.

Examples

let error = gpp::Error::TooManyParameters { command: "my_command" };
assert_eq!(format!("{}", error), "Too many parameters for #my_command");

let error = gpp::Error::FileError {
    filename: "my_file".to_string(),
    line: 10,
    error: Box::new(gpp::Error::UnexpectedCommand {
        command: "this_command",
    }),
};
assert_eq!(format!("{}", error), "Error in my_file:10: Unexpected command #this_command");

Variants

InvalidCommand

An unknown command was encountered.

Fields

command_name: String

TooManyParameters

Too many parameters were given for a command (for example using #endif with parameters).

Fields

command: &'static str

UnexpectedCommand

There was an unexpected command; currently only generated for unexpected #endins.

Fields

command: &'static str

ChildFailed

The child process for an #exec exited with a nonzero status.

Fields

status: ExitStatus

PipeFailed

A pipe was unable to be set up to the child.

IoError(Error)

An error with I/O occurred.

FromUtf8Error(FromUtf8Error)

An error occurred parsing a child’s standard output as UTF-8.

FileError

An error occurred in another file.

Fields

filename: String

line: usize

error: Box<Error>

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.

impl From<Error> for Error

fn from(e: Error) -> Self

Converts to this type from the input type.

impl From<FromUtf8Error> for Error

fn from(e: FromUtf8Error) -> Self

Converts to this type from the input type.
