Enum InitError 

pub enum InitError {
    Ambiguous {
        symbol: &'static Symbol,
    },
    Circular {
        symbols: Vec<&'static Symbol>,
    },
    Execution(Error),
}

Error type returned by init_static() when initialization fails.

This enum represents the various failure modes that can occur during the static initialization process.

Variants

Ambiguous

A static symbol was defined multiple times.

This typically occurs when the same init_static! block is included multiple times, or when two statics in different modules have the exact same source location metadata (which should not happen in normal usage).

Fields

symbol: &'static Symbol

Circular

A circular dependency was detected among statics.

This occurs when static A depends on static B, and static B (directly or indirectly) depends on static A. The initialization system cannot determine a valid order to initialize such statics.

Fields

symbols: Vec<&'static Symbol>

Execution(Error)

An initialization expression returned an error.

This wraps any anyhow::Error returned by a static’s initialization expression. The original error is preserved and can be accessed via the Error::source method.

Trait Implementations

impl Debug for InitError

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

Formats the value using the given formatter.

impl Display for InitError

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

Formats the value using the given formatter.

impl Error for InitError

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 InitError

fn from(e: Error) -> Self

Converts to this type from the input type.
