Enum MetadataConversionError 

pub enum MetadataConversionError {
    WrongType {
        expected: &'static str,
        found: &'static str,
    },
    NumberOutOfRange {
        expected: &'static str,
        found: Number,
    },
    FloatNotRepresentable,
}

Error type returned when attempting to convert (try_into) a MetadataValue into a concrete type and the value does not have the expected shape.

Variants

WrongType

Fields

expected: &'static str

found: &'static str

NumberOutOfRange

Fields

expected: &'static str

found: Number

FloatNotRepresentable

Returned when a floating point number cannot be represented (unlikely here, but preserved for completeness).

Trait Implementations

impl Clone for MetadataConversionError

fn clone(&self) -> MetadataConversionError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MetadataConversionError

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

Formats the value using the given formatter.

impl Display for MetadataConversionError

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

Formats the value using the given formatter.

impl Eq for MetadataConversionError

impl Error for MetadataConversionError

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 MetadataConversionError

fn eq(&self, other: &MetadataConversionError) -> 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.
