Struct FieldConstraint 

pub struct FieldConstraint {
    pub field: String,
    pub min: Option<u64>,
    pub max: Option<u64>,
    pub pattern: Option<String>,
    pub enum_values: Vec<String>,

    pub is_uuid: bool,
    pub is_numeric: bool,
    pub signed_min: Option<i64>,
    pub signed_max: Option<i64>,
}

A single field’s validation constraints, mapped to JSON Schema.

Fields

field: String

Field name in camelCase (gnostic output format).

min: Option<u64>

minLength for strings, minimum for integers.

max: Option<u64>

maxLength for strings, maximum for integers.

pattern: Option<String>

Regex pattern (from validate.rules.string.pattern).

enum_values: Vec<String>

Enum of allowed string values (from validate.rules.string.in).

required: bool

Whether this is a message.required field → goes into schema required array.

is_uuid: bool

Whether this is a UUID field (from validate.rules.string.uuid = true).

is_numeric: bool

Proto field type: true if numeric (int32/uint32/uint64), false if string.

signed_min: Option<i64>

minimum for signed integers (int32). Mutually exclusive with min. When present, the JSON Schema should use this instead of min.

signed_max: Option<i64>

maximum for signed integers (int32). Mutually exclusive with max. When present, the JSON Schema should use this instead of max.
