Enum demes::DemesError

#[non_exhaustive]
pub enum DemesError {
    DemeError(String),
    EpochError(String),
    GraphError(String),
    MigrationError(String),
    PulseError(String),
    YamlError(Error),
    JsonError(Error),
    ValueError(String),
}

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 (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future 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.

JsonError(Error)

Available on crate feature json only.

Errors coming from serde_json.

ValueError(String)

Errors related to low-level types

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 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.

impl From<Error> for DemesError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<Error> for DemesError

fn from(source: Error) -> Self

Converts to this type from the input type.
