Required Methods

fn transform<Q>(self, _: impl FnOnce(Self) -> Q) -> Q

where Self: Sized,

fn transform_if(self, _: bool, _: impl FnOnce(Self) -> Self) -> Self

where Self: Sized,

Example

Table::new(rows, widths.to_vec())
    .block(block)
    .transform_if(
        true,
        |t| t.style(style),
    )

fn modify<Q>(self, _: impl FnOnce(&mut Self) -> Q) -> Self

where Self: Sized,

fn modify_if<Q>(self, _: bool, _: impl FnOnce(&mut Self) -> Q) -> Self

where Self: Sized,

Example

use cba::bait::TransformExt;

true.modify_if(cfg!(debug_assertions), |x| *dbg!(x));

fn cmp_exch<'a, E>(&'a mut self, _: E, _: Self) -> bool

where &'a mut Self: PartialEq<E>,

Example

use cba::bait::TransformExt;

let mut v = 0usize;
if !v.cmp_exch(&mut 0, 1) {
    unreachable!();
}
assert_eq!(v, 1);

fn cmp_replace(&mut self, _: Self) -> bool

where Self: PartialEq,

Example

use cba::bait::TransformExt;

true.modify_if(cfg!(debug_assertions), |x| *dbg!(x));

fn dbg(self) -> Self

where Self: Debug,

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
