Struct ConversionError 

#[non_exhaustive]
pub struct ConversionError {
    pub expected: Kind,
    pub actual: Kind,
    pub context: Option<String>,
}

Error when converting between types

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

expected: Kind

The expected kind

actual: Kind

The actual kind that was received

context: Option<String>

Optional context about what was being converted

Implementations

impl ConversionError

pub fn new(expected: Kind, actual: Kind) -> Self

Create a new conversion error

pub fn from_value(expected: Kind, value: &Value) -> Self

Create a conversion error from a value

pub fn with_context(self, context: impl Into<String>) -> Self

Add context to the error

Trait Implementations

impl Clone for ConversionError

fn clone(&self) -> ConversionError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ConversionError

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

Formats the value using the given formatter.

impl Display for ConversionError

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

Formats the value using the given formatter.

impl Error for ConversionError

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 From<ConversionError> for Error

fn from(e: ConversionError) -> Self

Converts to this type from the input type.
