Struct PolicyParseError 

pub struct PolicyParseError {
    pub field: &'static str,
    pub value: String,
    pub expected: String,
}

A named choice (a policy decision, a spatial backend, a file format) was spelled with a word outside its vocabulary.

Fields

field: &'static str

Which decision was being read.

value: String

What was written.

expected: String

What would have been accepted, for the message.

Implementations

impl PolicyParseError

pub fn new(field: &'static str, value: &str, expected: &str) -> Self

A refusal of value for the choice named field, which would have accepted expected.

Trait Implementations

impl Clone for PolicyParseError

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PolicyParseError

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

impl Eq for PolicyParseError

impl Error for PolicyParseError

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.
