Struct VapError 

#[non_exhaustive]
pub struct VapError {
    pub expression: String,
    /* private fields */
}

Available on crate feature validation only.

An error produced when a VAP expression fails to compile.

Returned in the Err arm of VapEvaluator::compile_expressions. The underlying cel parse error is available via std::error::Error::source; the concrete cel type is kept out of the public surface (held behind a boxed dyn Error) so it is not frozen into the API.

#[non_exhaustive]: VAP compilation has a single failure mode today; new fields may be added without a breaking change.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

expression: String

The VAP expression that failed to compile.

Trait Implementations

impl Debug for VapError

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

Formats the value using the given formatter.

impl Display for VapError

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

Formats the value using the given formatter.

impl Error for VapError

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.
