Enum MergeKeyPolicy 

#[non_exhaustive]
pub enum MergeKeyPolicy {
    Merge,
    AsOrdinary,
    Error,
}

Merge key handling policy for YAML mappings.

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.

Merge

Expand YAML merge keys (<<) into the surrounding mapping, as per YAML 1.1 specs.

AsOrdinary

Treat YAML merge keys (<<) as ordinary mapping keys.

Error

Error out on encountering a YAML merge key (<<), reporting the location.

Trait Implementations

impl Clone for MergeKeyPolicy

fn clone(&self) -> MergeKeyPolicy

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MergeKeyPolicy

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

Formats the value using the given formatter.

impl Default for MergeKeyPolicy

fn default() -> MergeKeyPolicy

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for MergeKeyPolicy

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for MergeKeyPolicy

fn eq(&self, other: &MergeKeyPolicy) -> 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 MergeKeyPolicy

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
