Struct shades::scope::When

pub struct When<'a, S> { /* private fields */ }

Conditional combinator.

A When<S, R> is returned from functions such as [CanEscape::when] or [CanEscape::unless] and allows to continue chaining conditional statements, encoding the concept of else if and else in more traditional languages.

Implementations

impl<S> When<'_, S> where
    S: DeepScope + Erased<Erased = ErasedScope>, 

pub fn or_else(
    self,
    condition: impl Into<Expr<bool>>,
    body: impl FnOnce(&mut S)
) -> Self

Add a conditional branch — else if.

This method is often found chained after [CanEscape::when] and allows to add a new conditional if the previous conditional fails (i.e. else if). The behavior is the same as with [CanEscape::when].

Return

Another When<R>, allowing to add more conditional branches.

pub fn or(self, body: impl FnOnce(&mut S))

Add a final catch-all conditional branch — else.

This method is often found chained after [CanEscape::when] and allows to finish the chain of conditional branches if the previous conditional fails (i.e. else). The behavior is the same as with [CanEscape::when].

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

Formats the value using the given formatter.
