Errors arising while converting a policy from its JSON representation (aka EST) into an AST

Variants

JsonDeserializationError(JsonDeserializationError)

Error while deserializing JSON

TemplateToPolicy(UnexpectedSlotError)

Tried to convert an EST representing a template to an AST representing a static policy

InvalidSlotName

Slot name was not valid for the position it was used in. (Currently, principal slots must be named ?principal, and resource slots must be named ?resource.)

ActionSlot

EST contained a template slot for action. This is not currently allowed

MissingOperator

EST contained the empty JSON object {} where a key (operator) was expected

MultipleOperators

Fields

ops: Vec<SmolStr>

the multiple operators that were found where one was expected

EST contained an object with multiple keys (operators) where a single operator was expected

MultiplicationByNonConstant

Fields

arg1: Expr

First non-constant argument

arg2: Expr

Second non-constant argument

At most one of the operands in a * b * c * d * ... can be a non-{constant int}

UnescapeError(Vec<UnescapeError>)

Error thrown while processing string escapes

InvalidEntityType(ParseErrors)

Error reported when the entity type tested by an is expression cannot be parsed.

Trait Implementations

impl Debug for FromJsonError

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

Formats the value using the given formatter.

impl Display for FromJsonError

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

Formats the value using the given formatter.

impl Error for FromJsonError

fn source(&self) -> Option<&(dyn Error + 'static)>

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<JsonDeserializationError> for FromJsonError

fn from(source: JsonDeserializationError) -> Self

Converts to this type from the input type.

impl From<UnexpectedSlotError> for FromJsonError

fn from(source: UnexpectedSlotError) -> Self

Converts to this type from the input type.
