IoError

IoError

pub enum IoError

Classifies portable output and byte-stream failures.

OutputFailed preserves the original output identity. Failure carries a portable reason and already transferred byte prefix, never host errno. Counts are relative to the current operation, not cumulative stream position.

Example

module example.io_error;
from std.io import IoError, TryPrint;
fn Main() -> i32 {
    let ResultValue = TryPrint("ready");
    switch ResultValue {
        case .Ok => return 0;
        case .Err { Error = _ } => return 1;
    }
}

IoError.OutputFailed

OutputFailed;

Reports that canonical output could not accept the complete byte view.
