Struct KeyValues 

pub struct KeyValues<'a>(/* private fields */);

Represents a collection of key-value pairs.

Examples

use std::fmt::Write;
use spdlog::{
    formatter::{Formatter, FormatterContext},
    Record, StringBuf,
};

#[derive(Clone)]
struct MyFormatter;

impl Formatter for MyFormatter {
    fn format(
        &self,
        record: &Record,
        dest: &mut StringBuf,
        ctx: &mut FormatterContext,
    ) -> spdlog::Result<()> {
        dest.write_str(record.payload())
            .map_err(spdlog::Error::FormatRecord)?;
        for (key, value) in record.key_values() {
            write!(dest, " {}={}", key.as_str(), value).map_err(spdlog::Error::FormatRecord)?;
        }
        Ok(())
    }
}

Implementations

impl<'a> KeyValues<'a>

pub fn len(&self) -> usize

Gets the number of key-value pairs.

pub fn is_empty(&self) -> bool

Checks if there are no key-value pairs.

pub fn get(&self, key: Key<'_>) -> Option<Value<'a>>

Gets the value of the specified key.

pub fn iter(&self) -> KeyValuesIter<'a>

Gets an iterator over the key-value pairs.

Trait Implementations

impl<'a> IntoIterator for KeyValues<'a>

type Item = (Key<'a>, ValueBag<'a>)

The type of the elements being iterated over.

type IntoIter = KeyValuesIter<'a>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.
