Why a triangulated declaration was rejected at CurveRecipes::insert.

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.

OwnKey

A triangulated recipe was inserted under an own-currency key.

Fields

key: CollateralSpec

The key.

UnpairedKey

The key decomposes into no currency pair.

Fields

key: CollateralSpec

The key.

DegenerateVia

via is one of the key’s own currencies.

Fields

key: CollateralSpec

The key.

via: String

The hub as declared.

MissingSource

A source key the triangle needs resolves to nothing in this book.

Fields

key: CollateralSpec

The key.

source: CollateralSpec

The source key.

ChainedSource

A source key is itself triangulated: chains are not supported.

Fields

key: CollateralSpec

The key.

source: CollateralSpec

The source key.

AmbiguousHub

More than one hub closes the triangle.

Fields

key: CollateralSpec

The key.

hubs: Vec<String>

The closing hubs.

MixedSegments

A triangulated recipe carried a discount segment.

Fields

key: CollateralSpec

The key.

role: Role

The offending segment’s role.

Trait Implementations

impl Clone for TriangulatedRecipeError

fn clone(&self) -> TriangulatedRecipeError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TriangulatedRecipeError

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

Formats the value using the given formatter.

impl Display for TriangulatedRecipeError

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

Formats the value using the given formatter.

impl Eq for TriangulatedRecipeError

impl Error for TriangulatedRecipeError

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 PartialEq for TriangulatedRecipeError

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
