Enum MapError 

#[non_exhaustive]
pub enum MapError {
    Key(Table),
    Word {
        table: Table,
        key: String,
    },
    Empty {
        table: Table,
        key: String,
    },
    Unknown {
        table: Table,
        key: String,
        code: String,
    },
    National {
        code: String,
        source: CodeError,
    },
}

Why a map was refused.

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.

Key(Table)

A key is empty or holds a control character.

Word

A key maps to a word other than none.

Fields

table: Table

The table.

key: String

The key.

Empty

A key maps to an empty list.

Fields

table: Table

The table.

key: String

The key.

Unknown

A key maps to a code that is neither a priority category nor a declared national one.

Fields

table: Table

The table.

key: String

The key.

code: String

The code.

National

A declared national category is refused.

Fields

code: String

The category as declared.

source: CodeError

Why.

Trait Implementations

impl Clone for MapError

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MapError

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

Formats the value using the given formatter.

impl Display for MapError

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

Formats the value using the given formatter.

impl Eq for MapError

impl Error for MapError

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 MapError

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
