Enum EnvironmentError 

pub enum EnvironmentError {
    InvalidAction(String),
    RenderFailed(String),
    IoError(Error),
}

Error type for environment operations.

EnvironmentError captures failures that can occur during environment initialization, reset, or stepping. It provides detailed error messages and supports error chaining via the standard std::error::Error trait.

Variants

InvalidAction(String)

An invalid or out-of-bounds action was provided.

RenderFailed(String)

Rendering or display failed.

IoError(Error)

An I/O operation failed (wraps std::io::Error).

Trait Implementations

impl Debug for EnvironmentError

Formats the value using the given formatter.

impl Display for EnvironmentError

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

impl Error for EnvironmentError

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 EnvironmentError

fn from(error: Error) -> Self

Converts to this type from the input type.
