Struct datetime_string::ConversionError

pub struct ConversionError<T> { /* fields omitted */ }

Error with value before conversion.

Implementations

impl<T> ConversionError<T>

#[must_use]pub fn error(&self) -> Error

Returns the inner (validation) error.

Examples

// `rfc3339::FullTimeString` is only available when `alloc` feature is enabled.
#![cfg(feature = "alloc")]

use std::convert::TryFrom;
use datetime_string::{Error, rfc3339::FullTimeString};

let conv_err = FullTimeString::try_from("invalid time".to_owned()).unwrap_err();
let _: Error = conv_err.error();

#[must_use]pub fn value(&self) -> &T

Returns a reference to the value, which is failed to convert.

Examples

// `rfc3339::FullTimeString` is only available when `alloc` feature is enabled.
#![cfg(feature = "alloc")]

use std::convert::TryFrom;
use datetime_string::{Error, rfc3339::FullTimeString};

let conv_err = FullTimeString::try_from("invalid time".to_owned()).unwrap_err();
let source_val: &String = conv_err.value();
assert_eq!(source_val, "invalid time");

#[must_use]pub fn into_value(self) -> T

Returns the value, which is failed to convert.

Examples

// `rfc3339::FullTimeString` is only available when `alloc` feature is enabled.
#![cfg(feature = "alloc")]

use std::convert::TryFrom;
use datetime_string::{Error, rfc3339::FullTimeString};

let conv_err = FullTimeString::try_from("invalid time".to_owned()).unwrap_err();
let source_val: String = conv_err.into_value();
assert_eq!(source_val, "invalid time");

impl<T: Debug> Error for ConversionError<T>

fn source(&self) -> Option<&(dyn Error + 'static)>

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
