Enum DecodeError

Source
pub enum DecodeError {
    InvalidBencodexValueError,
    UnexpectedTokenError {
        token: u8,
        point: usize,
    },
}
Expand description

The error type which is returned from decoding a Bencodex value through Decode::decode.

Variants§

§

InvalidBencodexValueError

This should be used when it failed to decode. In future, it will be separated more and more.

§

UnexpectedTokenError

This should be used when it failed to decode because there is unexpected token appeared while decoding.

§Example

For example, The encoded bytes of BencodexValue::Number are formed as ‘i{}e’ (e.g., ‘i0e’, ‘i2147483647e’). If it is not satisified, it should be result through inside Err.

use bencodex::{ Decode, DecodeError };

//                     v -- should be b'0' ~ b'9' digit.
let vec = vec![b'i', b':', b'e'];
let error = vec.decode().unwrap_err();
let expected_error = DecodeError::UnexpectedTokenError {
    token: b':',
    point: 1,
};
assert_eq!(expected_error, error);

Fields

§token: u8
§point: usize
