Enum Layout 

#[non_exhaustive]
pub enum Layout {
    Auto,
    Compact,
    Expanded,
}

How a map or sequence is laid out by formats that have a choice.

use deser::hints::Layout;

Layout::Compact.set(state);
assert_eq!(Layout::of(state), Layout::Compact);

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

No preference, the format decides.

Compact

Keep the container compact, for instance on a single line (a flow collection in YAML, an inline table in TOML).

Expanded

Spread the container out, for instance one entry per line (a block collection in YAML, a section in TOML).

Implementations

impl Layout

pub fn of(state: &State) -> Layout

Returns the layout of the current event.

pub fn set(self, state: &mut State)

Sets the layout of the current event.

This is intended to be called from Serialize::serialize or a Layer, the layout applies to the value that is serialized.

Trait Implementations

impl Clone for Layout

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Layout

impl Debug for Layout

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

Formats the value using the given formatter.

impl Default for Layout

fn default() -> Self

Returns the “default value” for a type.

impl Eq for Layout

impl Hash for Layout

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 PartialEq for Layout

fn eq(&self, other: &Self) -> bool

Equality operator ==.

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

Inequality operator !=.
