Enum CollectionTypeParseError 

#[non_exhaustive]
pub enum CollectionTypeParseError {
    Unknown {
        input: String,
    },
    Deprecated {
        input: String,
        canonical: &'static str,
    },
}

Error returned by CollectionType’s std::str::FromStr impl when an unrecognised or deprecated engine name is supplied.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Unknown

The input string is not a recognised canonical engine name.

Fields

input: String

Deprecated

The input string is a deprecated alias; the canonical name is provided.

Fields

input: String

canonical: &'static str

Trait Implementations

impl Clone for CollectionTypeParseError

fn clone(&self) -> CollectionTypeParseError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CollectionTypeParseError

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

Formats the value using the given formatter.

impl Display for CollectionTypeParseError

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

Formats the value using the given formatter.

impl Error for CollectionTypeParseError

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 CollectionTypeParseError

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