Struct ReturnTails

struct ReturnTails<'a> {
    self_tail: Box<dyn Fn(&str, &str) -> Vec<String> + 'a>,
    chain_tail: Box<dyn Fn(&str) -> Vec<String> + 'a>,
    direct_tail: Box<dyn Fn(&str) -> Vec<String> + 'a>,
}

Expand description

Class-specific tail closures, one per ReturnStrategy variant.

Each closure receives (indent, class_name) and produces the tail lines that run after .val <- <call_expr> and the condition check (both emitted by MethodReturnBuilder::build_with_tails). The tail therefore always references .val directly.

class_name is "" for ReturnStrategy::ChainableMutation and ReturnStrategy::Direct — those tails should not use it.

Fields§

§self_tail: Box<dyn Fn(&str, &str) -> Vec<String> + 'a>

Tail for ReturnStrategy::ReturnSelf.

Parameters: (indent, class_name) -> lines

§chain_tail: Box<dyn Fn(&str) -> Vec<String> + 'a>

Tail for ReturnStrategy::ChainableMutation.

Parameters: (indent) -> lines

§direct_tail: Box<dyn Fn(&str) -> Vec<String> + 'a>

Tail for ReturnStrategy::Direct.

Parameters: (indent) -> lines

impl<T> SizeHint for T
where T: ?Sized,

Source §

default fn lower_bound(&self) -> usize

🔬This is a nightly-only experimental API. (core_io_internals)

Returns a lower bound on the number of elements this container-like item contains. For example, an array [u8; 12] could return any value between 0 and 12 inclusively as a correct implementation. Read more

default fn upper_bound(&self) -> Option<usize>

🔬This is a nightly-only experimental API. (core_io_internals)

Returns an upper bound on the number of elements this container-like item contains if it can be determined, otherwise None. Read more

Source §

final fn size_hint(&self) -> (usize, Option<usize>)

🔬This is a nightly-only experimental API. (core_io_internals)

Returns an estimate for the number of elements this container like type contains. Read more
