Struct Extensions 

pub struct Extensions { /* private fields */ }

Set of extensions of a Problem.

Implementations

impl Extensions

pub fn insert<K, V>(&mut self, key: K, value: V)

where K: Into<CowStr>, V: Serialize,

Add an extension into the set.

Panics

Panics if the serialization of V fails.

pub fn len(&self) -> usize

Number of extensions.

pub fn is_empty(&self) -> bool

If we have no extensions.

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

Formats the value using the given formatter.

impl Default for Extensions

fn default() -> Extensions

Returns the “default value” for a type.

impl<'e> IntoIterator for &'e Extensions

type IntoIter = ExtensionsIter<'e>

Which kind of iterator are we turning this into?

type Item = (&'e str, &'e Value)

The type of the elements being iterated over.

fn into_iter(self) -> Self::IntoIter
