Struct slog::OwnedKeyValueList

pub struct OwnedKeyValueList { /* fields omitted */ }

Chain of SyncMultiSerialize-s of a Logger and its ancestors

Methods

impl OwnedKeyValueList

fn new(values: Box<SyncMultiSerialize>, parent: OwnedKeyValueList) -> Self

New OwnedKeyValueList node with an existing parent

fn root(values: Option<Box<SyncMultiSerialize>>) -> Self

New OwnedKeyValue node without a parent (root)

fn parent(&self) -> &Option<OwnedKeyValueList>

Get the parent node element on the chain of values

Since OwnedKeyValueList is just a chain of SyncMultiSerialize instances: each containing one more more OwnedKeyValue, it's possible to iterate through the whole list group-by-group with parent() and values().

fn values(&self) -> Option<&SyncMultiSerialize>

Get the head node SyncMultiSerialize values

fn iter(&self) -> OwnedKeyValueListIterator

Iterator over all OwnedKeyValue-s in every SyncMultiSerialize of the list

The order is reverse to how it was built. Eg.

#[macro_use]
extern crate slog;

fn main() {
    let drain = slog::Discard;
    let root = slog::Logger::root(drain, o!("k1" => "v1", "k2" => "k2"));
    let _log = root.new(o!("k3" => "v3", "k4" => "v4"));
}

Will produce OwnedKeyValueList.iter() that returns k4, k3, k2, k1.

fn id(&self) -> usize

Deprecated

Get a unique stable identifier for this node

This function is buggy and will be removed at some point. Please see https://github.com/slog-rs/slog/issues/90

Trait Implementations

impl Clone for OwnedKeyValueList

fn clone(&self) -> OwnedKeyValueList

Returns a copy of the value.

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

Performs copy-assignment from source.
