Struct log::key_values::Key

pub struct Key<'k> { /* fields omitted */ }

The key in a key-value pair.

The Key type abstracts over owned or borrowed keys.

Methods

impl<'k> Key<'k>

pub fn from_owned(
    key: impl Into<String>,
    index: Option<usize>
) -> Self

Create a key from an owned string and optional index.

impl<'k> Key<'k>

pub fn from_str(
    key: &'k impl Borrow<str> + ?Sized,
    index: Option<usize>
) -> Self

Create a key from a borrowed string and optional index.

pub fn index(&self) -> Option<usize>

pub fn as_str(&self) -> &str
