Enum CVarError 

#[non_exhaustive]
pub enum CVarError {
    UnknownCVar,

Errors that can occur when manipulating CVars.

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.

UnknownCVar

Error indicating a CVar was never registered or is invalid.

BadCVarType

Error indicating the given CVar type is invalid.

MissingCid

Error indicating the CVar type is missing a ComponentId and is likely not registered correctly.

CannotDeserialize

Error indicating the underlying type of the CVar cannot be deserialized, and as such cannot be reflected over.

FailedDeserialize(String)

Error indicating the CVar failed to deserialize.

FailedApply

Error indicating applying a value to the CVar failed, containing the inner error.

Fields

inner: ApplyError

The inner error.

AccessConflict

Error indicating that the world could not fulfill the requested operation due to an access conflict with an ongoing operation.

TomlError(TomlError)

An error when parsing a TOML document.

MalformedConfigDuringWrite(&'static str)

An error when saving encounters malformed TOML structure.

TomlSerError(Error)

An error when serializing TOML data.

Trait Implementations

impl Debug for CVarError

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

Formats the value using the given formatter.

impl Display for CVarError

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

Formats the value using the given formatter.

impl Error for CVarError

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.
