Enum ValidationError 

pub enum ValidationError {
    InvalidAppCode(String),
    InvalidVersion(String),
    InvalidHookTarget {
        hook: String,
        reason: String,
    },
    InvalidHookGasLimit {
        gas_limit: String,
    },
    PartnerFeeBpsTooHigh(u32),
    UnknownOrderClass(String),
    InvalidReplacedOrderUid(String),
    SchemaViolation {
        path: String,
        message: String,
    },
}

A specific constraint violation found when validating an AppDataDoc.

Every variant carries enough context to display a useful diagnostic message via its Display implementation. Variants are returned inside ValidationResult::typed_errors for programmatic inspection.

Example

use cow_rs::app_data::{AppDataDoc, ValidationError, validate_app_data_doc};

let doc = AppDataDoc::new(""); // empty appCode triggers InvalidAppCode
let result = validate_app_data_doc(&doc);
assert!(result.errors_ref().iter().any(|e| matches!(e, ValidationError::InvalidAppCode(_))));

Variants

InvalidAppCode(String)

appCode is empty or exceeds 50 characters.

InvalidVersion(String)

metadata.version is not a valid semver string (x.y.z).

InvalidHookTarget

A hook target is not a valid Ethereum address (0x + 40 hex chars).

Fields

hook: String

The invalid target string.

reason: String

Human-readable reason.

InvalidHookGasLimit

A hook gasLimit is not parseable as a decimal u64.

Fields

gas_limit: String

The invalid gas-limit string.

PartnerFeeBpsTooHigh(u32)

partnerFee entry volumeBps / surplusBps / priceImprovementBps exceeds 10 000 (100 %).

UnknownOrderClass(String)

orderClass.orderClass contains an unrecognised variant.

InvalidReplacedOrderUid(String)

A replacedOrder UID is not 56 bytes (i.e. not "0x" + 112 hex chars).

SchemaViolation

A structural violation reported by the bundled JSON Schema validator in super::schema — e.g. a missing required field, an unknown property, or a value that does not match a regex / enum constraint.

Fields

path: String

JSON pointer into the instance that triggered the violation.

message: String

Human-readable description of the violation.

Trait Implementations

impl Clone for ValidationError

fn clone(&self) -> ValidationError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ValidationError

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

Formats the value using the given formatter.

impl Display for ValidationError

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

Formats the value using the given formatter.

impl PartialEq for ValidationError

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
