Struct Indent

pub struct Indent {
    unit: String,
    buff: String,
    mark: Vec<usize>,
}

A helper struct to keep track of indentation levels.

This will be most often used as part of the rendering context type for various Display$Format implementation.

Fields

unit: String

buff: String

mark: Vec<usize>

Implementations

impl Indent

pub fn new(unit: char, step: usize) -> Indent

Construct a new Indent where one level is represented by the given unit repeated step times.

fn inc(&mut self, rhs: usize)

fn dec(&mut self, rhs: usize)

pub fn set(&mut self)

Remember the current state.

pub fn reset(&mut self)

Reset buff to the last marked state.
