Struct FieldViolation 

pub struct FieldViolation {
    pub field: String,
    pub rule: &'static str,
    pub message: String,
    pub expected: Value,
    pub got: Option<Value>,
}

One field-level constraint violation, structured for a caller to read.

Fields

field: String

JSON-pointer-ish field path. Top-level field names (“code”), nested dotted paths (“config.timeout”), or array elements (“items[2]”).

rule: &'static str

Short rule identifier — "range", "one_of", "regex", "length", "exactly_one", "at_least_one", "all_of", "any_of", "not", "custom".

message: String

Human-readable description of what’s wrong.

expected: Value

Machine-readable description of the expected shape, e.g. {"min":100, "max":599} or {"one_of":["a","b"]} — exactly what the rule asserts.

got: Option<Value>

The actual value that violated, when extractable.
