Enum poke_a_mango::Error

pub enum Error {
    FileParsingFailed {
        desc: &'static str,
        errors: Vec<String>,
    },
    Io {
        desc: &'static str,

        error: String,
    },
}

Enum representing all possible ways the application can fail.

Variants

FileParsingFailed

Failed to parse the specified file because of the specified errors.

Fields of FileParsingFailed

desc: &'static str	The file that failed to parse.
errors: Vec<String>	The parsing errors that occured.

Io

An I/O error occured.

This includes higher-level I/O errors like FS ones.

Fields of Io

desc: &'static str	The file that failed to parse.
op: &'static str	The failed operation. This should be lowercase and imperative ("create", "open").

Ui

A UI error, like a failure to creat a Window.

Fields of Ui

desc: &'static str	The UI operation's description. This should be imperative.
error: String	The failed operation, as returned by the UI framework.

Methods

impl Error

pub fn print_error<W: Write>(&self, err_out: &mut W)

Get the executable exit value from an Error instance.

Examples

let mut out = Vec::new();
Error::Io {
    desc: "leaderboard",
    op: "write",
}.print_error(&mut out);
assert_eq!(String::from_iter(out.iter().map(|&i| i as char)),
           "Writing leaderboard failed.\n".to_string());

pub fn exit_value(&self) -> i32

Get the executable exit value from an Error instance.

Examples

assert_eq!(Error::FileParsingFailed {
    desc: "",
    errors: vec![],
}.exit_value(), 1);

Trait Implementations

impl Debug for Error

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Clone for Error

fn clone(&self) -> Error

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Hash for Error

fn hash<__H: Hasher>(&self, __arg_0: &mut __H)

Feeds this value into the given [Hasher].

fn hash_slice<H>(data: &[Self], state: &mut H) where
    H: Hasher, 

Feeds a slice of this type into the given [Hasher].

impl PartialEq for Error

fn eq(&self, __arg_0: &Error) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, __arg_0: &Error) -> bool

This method tests for !=.
