Struct ConversionError

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

Error with value before conversion.

Implementations

impl<T> ConversionError<T>

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();

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");

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");

Trait Implementations

impl<T: Clone> Clone for ConversionError<T>

fn clone(&self) -> ConversionError<T>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

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

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

Formats the value using the given formatter.

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

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

Formats the value using the given formatter.

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

Available on crate feature std only.

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.
