Enum WalkError 

pub enum WalkError {
    InvalidConfig(String),
    BoxError(String),
    DeadEnd {
        chain: usize,
        monomer: usize,
    },
}

Errors returned by SelfAvoidingWalk::generate.

Variants

InvalidConfig(String)

A configuration field is out of range (non-positive length/density, zero chain length or chain count, or a box too small for the bond length).

BoxError(String)

The simulation box could not be constructed.

DeadEnd

The walk trapped itself: per-step retries, backtracking, and whole-chain restarts were all exhausted. monomer is the furthest length reached.

Fields

chain: usize

Index of the chain that failed to complete.

monomer: usize

Furthest monomer count reached on that chain across all attempts.

Trait Implementations

impl Clone for WalkError

fn clone(&self) -> WalkError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WalkError

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

Formats the value using the given formatter.

impl Display for WalkError

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

Formats the value using the given formatter.

impl Error for WalkError

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.

impl From<BoxError> for WalkError

fn from(e: BoxError) -> Self

Converts to this type from the input type.

impl PartialEq for WalkError

fn eq(&self, other: &WalkError) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
