Enum WrapOptions 

pub enum WrapOptions<'a> {
    NoWrap,
    WrapAt(usize),
    WrapAtWith(usize, &'a str),
}

Line Wrapping Options.

Used with encode and encode_buf. See them for examples.

Unless you want to specify a custom end-of-line string, use an Option::None instead for no wrapping or an usize instead for wrapping at a column boundary, and everything will magically work.

Variants

NoWrap

Don’t wrap lines at all

WrapAt(usize)

Wrap every so many columns with ‘\n’. The length must be > 0.

WrapAtWith(usize, &'a str)

Wrap every so many columns with a specified string. The length must be > 0.

Trait Implementations

impl<'a> Clone for WrapOptions<'a>

fn clone(&self) -> WrapOptions<'a>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'a> Debug for WrapOptions<'a>

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

Formats the value using the given formatter.

impl<'a, T> From<T> for WrapOptions<'a>

where T: Into<Option<usize>>,

fn from(from: T) -> Self

Converts to this type from the input type.

impl<'a> Hash for WrapOptions<'a>

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<'a> PartialEq for WrapOptions<'a>

fn eq(&self, other: &WrapOptions<'a>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
