Enum NovaError 

pub enum NovaError {
    DatabaseError(String),
    ValidationError(String),
    AuthenticationError(String),
    AuthorizationError(String),
    NotFound(String),
    Conflict(String),
    InternalError(String),
    BadRequest(String),
    Custom {
        status: StatusCode,
        error: String,
        message: String,
    },
}

Nova framework error types.

Use NovaError for returning typed, HTTP-aware errors from handlers and library code. It implements IntoResponse so it can be returned directly from Axum handlers.

Variants

DatabaseError(String)

Database connection or query errors

ValidationError(String)

Validation failed

AuthenticationError(String)

Authentication failed

AuthorizationError(String)

Authorization failed (forbidden)

NotFound(String)

Conflict(String)

Conflict error (e.g., duplicate entry)

InternalError(String)

Internal server error

BadRequest(String)

Bad request / Invalid input

Custom

Custom error with status code

Fields

status: StatusCode
