Enum IgraphError 

pub enum IgraphError {
    InvalidArgument(String),
    VertexOutOfRange {
        id: u32,
        n: u32,
    },
    EdgeOutOfRange {
        id: u32,

    DidNotConverge {
        iters: usize,
        residual: f64,
    },
    Internal(&'static str),
}

All errors returned from rust-igraph.

Variants are added as algorithms land; the initial set covers the cases the walking-skeleton (Phase 0) needs.

Variants

InvalidArgument(String)

Argument was outside its accepted range or otherwise invalid.

VertexOutOfRange

A vertex id referred to a vertex that does not exist.

Fields

id: u32

n: u32

EdgeOutOfRange

An edge id referred to an edge that does not exist.

Fields

id: u32

m: u32

Io(Error)

An I/O failure while reading or writing graph data.

Parse

Parsing a graph file failed.

Fields

line: usize

message: String

Unsupported(&'static str)

Operation is not supported (e.g. unweighted-only path requested on weighted graph).

DidNotConverge

Numeric algorithm failed to converge within iteration budget.

Fields

iters: usize

residual: f64

Internal(&'static str)

Catch-all for unexpected internal failures (bugs).

Trait Implementations

impl Debug for IgraphError

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

Formats the value using the given formatter.

impl Display for IgraphError

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

Formats the value using the given formatter.

impl Error for IgraphError

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<Error> for IgraphError

fn from(source: Error) -> Self

Converts to this type from the input type.
