Enum FoldStyle 

#[non_exhaustive]
pub enum FoldStyle {
    Auto,
    Fixed,
    None,
}

Controls how long strings are folded across lines using / continuation markers.

• Auto (default): prefer folding immediately after EOL characters, and at whitespace to word boundaries to fit wrap_width.
• Fixed: fold right at, or if it violates specification (e.g. not between two data characters), immediately before, wrap_width.
• None: do not fold, even if it means overflowing past wrap_width.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Auto

Prefer folding immediately after EOL characters, and at whitespace to word boundaries to fit wrap_width.

Fixed

Fold right at, or if it violates specification (e.g. not between two data characters), immediately before, wrap_width.

None

Do not fold, even if it means overflowing past wrap_width.

Trait Implementations

impl Clone for FoldStyle

fn clone(&self) -> FoldStyle

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FoldStyle

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

Formats the value using the given formatter.

impl Default for FoldStyle

fn default() -> FoldStyle

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for FoldStyle

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl FromStr for FoldStyle

type Err = String

The associated error which can be returned from parsing.

fn from_str(input: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl PartialEq for FoldStyle

fn eq(&self, other: &FoldStyle) -> 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.

impl Serialize for FoldStyle

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for FoldStyle

impl Eq for FoldStyle

impl StructuralPartialEq for FoldStyle
