Struct log::key_values::value::Value

pub struct Value<'v>(_);

The value in a key-value pair.

Methods

impl<'v> Value<'v>

pub fn visit(&self, visitor: &mut dyn Visitor) -> Result<(), Error>

Visit a value using a Visitor.

impl<'v> Value<'v>

pub fn from_debug(
    v: &'v impl Debug
) -> Self

Create a value from a fmt::Debug.

impl<'v> Value<'v>

pub fn from_sval(
    v: &'v impl Value + Debug
) -> Self

Create a value from a sval::Value.

impl<'v> Value<'v>

pub fn from_serde(
    v: &'v impl Serialize + Debug
) -> Self

Create a value from a serde::Serialize.

impl<'v> Value<'v>

pub fn from_any<T>(
    v: &'v T,
    from: fn(_: FromAny, _: &T) -> Result<(), Error>
) -> Self

Create a value from some type.

The value must be provided with a compatible from method, but doesn't need to implement any traits. This method is useful when the type T can't satisfy the requirements for other Value::from methods, but the lifetime 'v prevents local new-types from being used.
