Struct serde_yaml::mapping::VacantEntry

source · [−]

pub struct VacantEntry<'a> { /* private fields */ }

Expand description

A view into a vacant entry in a Mapping. It is part of the Entry enum.

Implementations

source

impl<'a> VacantEntry<'a>

source

pub fn key(&self) -> &Value

Gets a reference to the key that would be used when inserting a value through the VacantEntry.

source

pub fn insert(self, value: Value) -> &'a mut Value

Sets the value of the entry with the VacantEntry’s key, and returns a mutable reference to it.

U: TryFrom<T>,

type Error = >::Error

The type returned in the event of a conversion error.

const: unstable · source

fn try_into(self) -> Result<U, >::Error>

Performs the conversion.
