Struct CsvColumnSpec 

pub struct CsvColumnSpec {
    pub index: usize,
    pub name: String,
    pub labels: Option<HashMap<String, String>>,
}

Specification for a single CSV column in a multi-column csv_replay configuration.

When the columns field is set on a CsvReplay generator config, each CsvColumnSpec specifies a column index and the metric name to use when that column is expanded into its own independent scenario.

Example YAML

columns:
  - index: 1
    name: cpu_percent
  - index: 2
    name: mem_percent

Fields

index: usize

Zero-based column index in the CSV file.

name: String

Metric name for the expanded scenario.

labels: Option<HashMap<String, String>>

Optional per-column labels merged with scenario-level labels during expansion. Column labels override scenario-level labels on key conflict.

Trait Implementations

impl Clone for CsvColumnSpec

fn clone(&self) -> CsvColumnSpec

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for CsvColumnSpec

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for CsvColumnSpec

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for CsvColumnSpec

fn eq(&self, other: &CsvColumnSpec) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for CsvColumnSpec

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for CsvColumnSpec
