Struct DebugList 

pub struct DebugList<'a> { /* private fields */ }

A helper designed to assist with creation of DebugPls implementations for list-like structures.

Examples

use dbg_pls::{pretty, DebugPls, Formatter};

struct Foo(Vec<i32>);

impl DebugPls for Foo {
    fn fmt(&self, f: Formatter<'_>) {
        f.debug_list().entries(&self.0).finish()
    }
}

let value = Foo(vec![10, 11]);
assert_eq!(format!("{}", pretty(&value)), "[10, 11]");

Implementations

impl<'a> DebugList<'a>

pub fn entry(self, entry: &dyn DebugPls) -> Self

Adds a new entry to the list output.

pub fn entries<D, I>(self, entries: I) -> Self

where D: DebugPls, I: IntoIterator<Item = D>,

Adds all the entries to the list output.

pub fn finish(self)

Closes off the list

Trait Implementations

impl<'f, D: DebugPls> Extend<D> for DebugList<'f>

fn extend<T: IntoIterator<Item = D>>(&mut self, iter: T)

Extends a collection with the contents of an iterator.

fn extend_one(&mut self, item: A)

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

Extends a collection with exactly one element.

fn extend_reserve(&mut self, additional: usize)

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

Reserves capacity in a collection for the given number of additional elements.
