Enum demes::DemesError

pub enum DemesError {
    DemeError(String),
    EpochError(String),
    GraphError(String),
    MigrationError(String),
    PulseError(String),
    YamlError(Error),
}

Error type for this crate.

The enum fields correspond to the different parts of a Graph defined by the specification.

Example

This input is incorrect because the epoch fails to define start_size or end_size. Attempting to generate a Graph gives DemesError::EpochError.

let yaml = "
time_units: generations
demes:
 - name: A
   epochs:
    - end_time: 100
";
assert!(matches!(demes::loads(yaml), Err(demes::DemesError::EpochError(_))));

Variants

DemeError(String)

Errors related to demes

EpochError(String)

Errors related to epochs

GraphError(String)

Top-level errors.

MigrationError(String)

Errors related to migrations

PulseError(String)

Errors related to pulses

YamlError(Error)

Errors coming from serde_yaml.

Trait Implementations

impl Debug for DemesError

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

Formats the value using the given formatter.

impl Display for DemesError

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

Formats the value using the given formatter.

impl Error for DemesError

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

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

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

Returns a stack backtrace, if available, of where this error occurred.

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

impl From<Error> for DemesError

fn from(error: Error) -> Self

Converts to this type from the input type.
