Struct DynKindMismatch 

pub struct DynKindMismatch {
    pub got: Vec<DynKind>,
    pub expected: &'static [&'static [DynKind]],
}

Returned by _dyn wrappers when the input combination has no static algorithm impl.

Example: distance_dyn(&Polygon, &Polygon) — v1 has no polygon-to-polygon distance impl yet. The wrapper returns Err(DynKindMismatch { got: [Polygon, Polygon], expected: &[...] }) rather than panicking.

Fields

got: Vec<DynKind>

The actual kinds of the inputs, in argument order.

expected: &'static [&'static [DynKind]]

The kind combinations the algorithm supports. Each inner slice is one supported argument list.

Trait Implementations

impl Eq for DynKindMismatch

impl Error for DynKindMismatch

Available on crate feature std only.

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.
