Struct PolicyError 

pub struct PolicyError(/* private fields */);

Error type returned by policy check / resolve methods.

Wraps a human-readable denial reason. Implements std::error::Error so it composes naturally with mlua::LuaError::external.

Implementations

impl PolicyError

pub fn new(message: impl Into<String>) -> Self

Create a new policy error from a message.

pub fn message(&self) -> &str

The denial reason.

Trait Implementations

impl Clone for PolicyError

fn clone(&self) -> PolicyError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

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, f: &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<&str> for PolicyError

fn from(s: &str) -> Self

Converts to this type from the input type.

impl From<String> for PolicyError

fn from(s: String) -> Self

Converts to this type from the input type.
