Struct Trailing

pub struct Trailing<T>(/* private fields */);

A wrapper type without an implementation of Deserialize which allows a special implementation of Wrap for functions that take a trailing default parameter.

Implementations

impl<T: DeserializeOwned> Trailing<T>

pub fn unwrap_or(self, other: T) -> T

Returns a underlying value if present or provided value.

pub fn unwrap_or_else<F: FnOnce() -> T>(self, f: F) -> T

Returns an underlying value or computes it if not present.

impl<T: Default + DeserializeOwned> Trailing<T>

pub fn unwrap_or_default(self) -> T

Returns an underlying value or the default value.

Trait Implementations

impl<T> From<Option<T>> for Trailing<T>

fn from(o: Option<T>) -> Self

Converts to this type from the input type.

impl<T> Into<Option<T>> for Trailing<T>

fn into(self) -> Option<T>

Converts this type into the (usually inferred) input type.
