Errors arising while converting EST to 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

SlotsInConditionClause

EST contained a template slot in policy condition

Fields

slot: SlotId

Slot that was found in a when/unless clause

clausetype: &'static str

Clause type, e.g. “when” or “unless”

MissingOperator

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

MultipleOperators

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

Fields

ops: Vec<SmolStr>

the multiple operators that were found where one was expected

MultiplicationByNonConstant

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

Fields

arg1: Expr

First non-constant argument

arg2: Expr

Second non-constant argument

UnescapeError(Vec<UnescapeError>)

Error thrown while processing string escapes

Trait Implementations

impl Debug for EstToAstError

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

Formats the value using the given formatter.

impl Display for EstToAstError

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

Formats the value using the given formatter.

impl Error for EstToAstError

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<JsonDeserializationError> for EstToAstError

fn from(source: JsonDeserializationError) -> Self

Converts to this type from the input type.

impl From<UnexpectedSlotError> for EstToAstError

fn from(source: UnexpectedSlotError) -> Self

Converts to this type from the input type.
