The stable failure codes.

Variants

DslParseError

The DSL source does not parse (reader or layout error).

DslTypeError

The DSL program does not type check, or names something unknown.

StreamReused

A one-shot stream was consumed twice.

StreamabilityUnknown

The plan’s streamability could not be established in strict mode.

InputOrderViolation

Input arrived in an order the plan’s contract forbids (a row before its metadata).

CaptureOverlapUnsupported

Two captures select overlapping scopes.

MissingValue

A required value is absent and no policy maps it.

DuplicateMember

An object repeats a member name under a policy that rejects that.

InvalidNumber

A number lexeme is not a valid number for the target.

ProtocolOrderError

A protocol event arrived out of sequence (a row before the schema, two schemas, a row of the wrong width, a missing end).

TargetValueUnrepresentable

The target format cannot represent the value (NaN in JSON, a table with no columns in CSV).

ResourceLimitExceeded

A configured limit was exceeded.

InputInvalid

The input did not parse, or is invalid for the source.

OutputFailed

Writing the output failed.

Aborted

The run was cancelled.

Implementations

impl Code

pub const ALL: [Code; 15]

Every code, in declaration order (for documentation checks).

pub fn as_str(self) -> &'static str

The code as it is written in every output: SCREAMING_SNAKE_CASE.

pub fn parse(text: &str) -> Option<Code>

A code by its written form.

Trait Implementations

impl Clone for Code

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Code

impl Debug for Code

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

Formats the value using the given formatter.

impl Display for Code

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

Formats the value using the given formatter.

impl Eq for Code

impl Hash for Code

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Code

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
