Enum PolicyError 

pub enum PolicyError {
    Io(Error),
    Toml(Error),
    ExprParse(String),
    RequirementExpression {
        name: String,
        source: Box<PolicyError>,
    },
    UnknownRequirement {
        name: String,
    },
    InvalidAliasEntry {
        canonical: String,
        entry: String,
    },
}

Error returned by the policy parser and validator.

Variants

Io(Error)

I/O error reading the policy file.

Toml(Error)

TOML parse error.

ExprParse(String)

A requirement expression failed to parse (bad token, trailing tokens, unbalanced parens, empty input, etc.).

RequirementExpression

A requirement’s condition expression failed to parse. Carries the requirement name as context; the wrapped error is the underlying ExprParse.

Fields

name: String

The requirement whose expression failed to parse.

source: Box<PolicyError>

The underlying parse error.

UnknownRequirement

An [[override]] block references a requirement name that isn’t defined in [requirement].

Fields

name: String

The name referenced by the override.

InvalidAliasEntry

An [alias] entry isn’t in log:claim-name form (missing the : separator).

Fields

canonical: String

The canonical claim name the alias was being defined for.

entry: String

The offending right-hand-side entry.

Trait Implementations

impl Debug for PolicyError

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

Formats the value using the given formatter.

impl Display for PolicyError

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

Formats the value using the given formatter.

impl Error for PolicyError

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 PolicyError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<Error> for PolicyError

fn from(source: Error) -> Self

Converts to this type from the input type.
