Enum VendorError 

pub enum VendorError {
    InvalidField {
        vendor_id: String,
        field: String,
        value: String,
        reason: String,
    },
    MissingField {
        vendor_id: String,
        field: String,
    },
    DuplicateId {
        vendor_id: String,
    },
    UnknownVendorId {
        vendor_id: String,
    },
    TomlParse(Error),
}

Errors returned by vendor-definition validation and loading.

Every variant embeds the vendor id and, where applicable, the field path (a dotted path such as signals[2].weight) plus the bad value as a string. The Display impl formats all three so the operator-facing message is actionable without any auxiliary lookup.

Variants

InvalidField

A field failed semantic validation (empty pattern, out-of-range weight, unknown source, etc.).

Fields

vendor_id: String

Vendor containing the offending field.

field: String

Field path (dotted JSON-pointer-style).

value: String

String form of the bad value.

reason: String

Human-readable reason the value was rejected.

MissingField

A required field is missing from the TOML payload.

Fields

vendor_id: String

Vendor missing the field.

field: String

Field path (dotted JSON-pointer-style).

DuplicateId

The same vendor id appears more than once in the input bundle.

Fields

vendor_id: String

Conflicting vendor id.

UnknownVendorId

The vendor id from the TOML does not match the crate::vendor_classifier::VendorId taxonomy.

Fields

vendor_id: String

Vendor id the loader did not recognise.

TomlParse(Error)

The TOML parser reported a structural error.

Implementations

impl VendorError

pub fn invalid_field( vendor_id: impl Into<String>, field: impl Into<String>, value: impl Display, reason: impl Into<String>, ) -> Self

Convenience constructor for VendorError::InvalidField.

pub fn missing_field( vendor_id: impl Into<String>, field: impl Into<String>, ) -> Self

Convenience constructor for VendorError::MissingField.

pub fn field_path(&self) -> Option<&str>

Field path (dotted JSON-pointer-style) when applicable.

pub fn bad_value(&self) -> Option<&str>

Bad value (string form) when applicable.

Trait Implementations

impl Debug for VendorError

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

Formats the value using the given formatter.

impl Display for VendorError

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

Formats the value using the given formatter.

impl Error for VendorError

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<Error> for VendorError

fn from(source: Error) -> Self

Converts to this type from the input type.
