Struct ValidationRule 

pub struct ValidationRule {
    pub logic: Value,
    pub message: String,
    pub logic_index: Option<usize>,
}

A single validation rule with a condition and error message.

The rule’s logic is evaluated against the message context. If it does not return exactly true, the validation fails and the error message is recorded.

Fields

logic: Value

JSONLogic expression that must evaluate to true for validation to pass. Any other result (false, null, etc.) is considered a validation failure.

message: String

Error message to display if validation fails. Defaults to “Validation failed” if not specified.

logic_index: Option<usize>

Index into the compiled logic cache. Set during workflow compilation.
