Enum MapError 

pub enum MapError {
    Invalid(String),
    Budget(String),
    Unsupported(String),
    Io(String),
    Terrain(String),
    Internal(String),
}

Errors are typed so callers can distinguish invalid input, budgets and unsupported cases.

Variants

Invalid(String)

Budget(String)

Unsupported(String)

Io(String)

Terrain(String)

Internal(String)

A caught panic or broken internal invariant (never a silent partial result).

Implementations

impl MapError

pub fn kind(&self) -> &'static str

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, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

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 From<Error> for MapError

fn from(e: Error) -> Self

Converts to this type from the input type.

impl PartialEq for MapError

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

Equality operator ==.

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

Inequality operator !=.
