Schema validation and evolution errors.

Variants

EmptyName

Name is empty.

Fields

label: String

Which entity had the empty name (e.g., “measurement name”, “tag key”).

NameTooLong

Name exceeds maximum length.

Fields

label: String

Which entity exceeded the limit.

length: usize

Actual byte length.

max: usize

Maximum allowed length.

NullByte

Name contains null byte.

Fields

label: String

Which entity contained the null byte.

InvalidCharacter

Name/value contains a character that would break the canonical form encoding (e.g. = in tag values).

Fields

label: String

Which entity contained the invalid character.

ch: char

The forbidden character.

value: String

The offending value for diagnostic context.

TooManyTags

Too many tags on a series key.

Fields

count: usize

Actual tag count.

max: usize

Maximum allowed.

EmptyFields

Point has no fields.

TooManyFields

Too many fields on a single point.

Fields

count: usize

Actual field count.

max: usize

Maximum allowed.

InvalidFieldValue

A field value failed validation (e.g., non-finite f64, oversized string).

Fields

field: String

Field name with the invalid value.

reason: String

Why the value is invalid.

TypeConflict

Type conflict: a field already exists with a different type.

Fields

measurement: String

Measurement name where the conflict occurred.

field: String

Field name with the type conflict.

expected: String

The existing (expected) type.

got: String

The conflicting (received) type.

DecimalScaleConflict

A decimal value carries more fractional digits than its column declares, so storing it would have to round.

Separate from TypeConflict because the fix is different: the types agree, the scale does not, and the writer either rounds the value itself or declares the column with the scale it needs before the first write.

Fields

measurement: String

Measurement name where the conflict occurred.

field: String

Field name with the scale conflict.

declared: u8

The column’s declared scale.

got: u8

The value’s scale.

value: String

The offending value, rendered exactly.

MeasurementNotFound(String)

Measurement not found.

LockPoisoned(String)

Internal lock was poisoned (indicates a prior panic while holding the lock).

InvalidName

An entity name failed validation.

Fields

name: String

The invalid name.

reason: String

Why the name is invalid.

Trait Implementations

impl Clone for SchemaError

fn clone(&self) -> SchemaError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SchemaError

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

Formats the value using the given formatter.

impl Display for SchemaError

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

Formats the value using the given formatter.

impl Eq for SchemaError

impl Error for SchemaError

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<SchemaError> for ChronixError

fn from(source: SchemaError) -> Self

Converts to this type from the input type.

impl PartialEq for SchemaError

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

Equality operator ==.

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

Inequality operator !=.

impl StructuralPartialEq for SchemaError
