Enum SessionError 

pub enum SessionError {
    ValidationFailed(Vec<ValidationError>),
    UnknownId(String),
    NoSnapshotAtTime {
        requested_t: f64,
    },
    InvalidPhase {
        expected: String,
        actual: String,
    },
    HydraulicSolve(HydraulicError),
    QualityEngine(QualityError),
}

Errors returned by the session API (§8.4).

Variants

ValidationFailed(Vec<ValidationError>)

The data model failed one or more validation checks (§2.9).

UnknownId(String)

The requested object ID does not exist in the loaded network.

NoSnapshotAtTime

A result was requested for a time that has no recorded snapshot.

Fields

requested_t: f64

The requested simulation time (seconds).

InvalidPhase

The operation is not valid in the current session phase.

Fields

expected: String

Phase name expected for this operation.

actual: String

Actual phase at the time of the call.

HydraulicSolve(HydraulicError)

The hydraulic solver encountered an error.

QualityEngine(QualityError)

The quality engine encountered an error.

Trait Implementations

impl Clone for SessionError

fn clone(&self) -> SessionError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SessionError

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

Formats the value using the given formatter.

impl Display for SessionError

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

Formats the value using the given formatter.

impl Error for SessionError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.
