Struct CommandHistogram

pub struct CommandHistogram {
    pub calls: usize,
    pub histogram_usec: HashMap<u32, u32>,
}

Command Histogram for the latency_histogram commands.

Fields

calls: usize

The total calls for that command.

histogram_usec: HashMap<u32, u32>

A map of time buckets:

• Each bucket represents a latency range.
• Each bucket covers twice the previous bucket’s range.
• Empty buckets are not printed.
• The tracked latencies are between 1 microsecond and roughly 1 second.
• Everything above 1 sec is considered +Inf.
• At max there will be log2(1000000000)=30 buckets.

Trait Implementations

impl Default for CommandHistogram

fn default() -> CommandHistogram

Returns the “default value” for a type.

impl FromValue for CommandHistogram

fn from_value(value: Value) -> Result<Self>

Used to do Value to user type conversion

fn from_value_with_command(value: Value, _command: &Command) -> Result<Self>

fn next_functor<I: Iterator<Item = Value>>() -> Box<dyn FnMut(&mut I) -> Option<Result<Self>>>
