Implementations
sourceimpl<'a> Entry<'a>
impl<'a> Entry<'a>
sourcepub fn or_insert(self, default: Value) -> &'a mut Value
pub fn or_insert(self, default: Value) -> &'a mut Value
Ensures a value is in the entry by inserting the default if empty, and returns a mutable reference to the value in the entry.
sourcepub fn or_insert_with<F>(self, default: F) -> &'a mut Value where
F: FnOnce() -> Value,
pub fn or_insert_with<F>(self, default: F) -> &'a mut Value where
F: FnOnce() -> Value,
Ensures a value is in the entry by inserting the result of the default function if empty, and returns a mutable reference to the value in the entry.
