[−][src]Enum termimage::Error
Enum representing all possible values the application can fail.
Variants
GuessingFormatFailed(String)
Failed to guess the image format.
OpeningImageFailed(String)
Failed to open image file.
Methods
impl Error
[src]
pub fn print_error<W: Write>(&self, err_out: &mut W)
[src]
Get the executable exit value from an Error
instance.
Examples
let mut out = Vec::new(); Error::GuessingFormatFailed("not_image.rs".to_string()).print_error(&mut out); assert_eq!(String::from_iter(out.iter().map(|&i| i as char)), "Failed to guess format of \"not_image.rs\".\n".to_string());
pub fn exit_value(&self) -> i32
[src]
Get the executable exit value from an Error
instance.
Examples
assert_eq!(Error::GuessingFormatFailed("".to_string()).exit_value(), 1); assert_eq!(Error::OpeningImageFailed("".to_string()).exit_value(), 2);
