Enum EventHashParseError 

pub enum EventHashParseError {
    InvalidLength(usize),
    InvalidChar {
        position: usize,
        ch: char,
    },
}

Error returned when parsing an EventHash from a hex string fails.

Args

• InvalidLength — the input was not exactly 40 hex characters
• InvalidChar — the input contained a non-hex character

Usage

use auths_core::witness::EventHash;
use std::str::FromStr;

assert!(EventHash::from_str("not-hex").is_err());

Variants

InvalidLength(usize)

The input string was not exactly 40 hex characters.

InvalidChar

The input contained a non-hex character at the given position.

Fields

position: usize

Zero-based index of the first invalid character.

ch: char

The character that failed hex decoding.

Trait Implementations

impl Debug for EventHashParseError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for EventHashParseError

fn fmt(&self, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for EventHashParseError

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 PartialEq for EventHashParseError

fn eq(&self, other: &EventHashParseError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
