Struct metrics_prometheus::recorder::layer::Stack

source · 
pub struct Stack<Head = Identity, Tail = Identity>(/* private fields */);
Expand description

metrics::Layer similar to metrics::layers::Stack, but nests the metrics::Layers themselves instead of metrics::Recorders.

Implementations§

source§

impl Stack

source

pub const fn identity() -> Self

Returns a growable Stack of metrics::Layers, being no-op by default.

source§

impl<H, T> Stack<H, T>

source

pub const fn push<R, L: Layer<R>>(self, layer: L) -> Stack<L, Self>

Pushes the provided metrics::Layer on top of this Stack, wrapping it.
