Struct Evidence 

pub struct Evidence {
    pub label: String,
    pub data: EvidenceData,
}

A piece of structured evidence backing a CheckResult.

Use this to attach decision-grade data (numbers, key-value pairs, code snippets, file refs) instead of formatting them into the free-form detail field. Consumers can read the typed payload directly without parsing text.

Example

use dev_report::{CheckResult, Evidence};

let check = CheckResult::pass("bench::parse")
    .with_evidence(Evidence::numeric("mean_ns", 1234.0))
    .with_evidence(Evidence::numeric("baseline_ns", 1100.0));

assert_eq!(check.evidence.len(), 2);

Fields

label: String

Short human-readable label (e.g. "ops_per_sec").

data: EvidenceData

Typed payload.

Implementations

impl Evidence

pub fn numeric(label: impl Into<String>, value: f64) -> Self

Build a numeric-evidence attachment.

Example

use dev_report::Evidence;

let e = Evidence::numeric("ops_per_sec", 12_500.0);
assert_eq!(e.label, "ops_per_sec");

pub fn kv<I, K, V>(label: impl Into<String>, pairs: I) -> Self

where I: IntoIterator<Item = (K, V)>, K: Into<String>, V: Into<String>,

Build a key-value-evidence attachment from any iterable of pairs.

Example

use dev_report::Evidence;

let e = Evidence::kv("env", [("RUST_LOG", "debug"), ("CI", "true")]);
assert_eq!(e.label, "env");

pub fn snippet(label: impl Into<String>, text: impl Into<String>) -> Self

Build a snippet-evidence attachment.

Example

use dev_report::Evidence;

let e = Evidence::snippet("panic", "thread 'main' panicked at ...");
assert_eq!(e.label, "panic");

pub fn file_ref(label: impl Into<String>, path: impl Into<String>) -> Self

Build a file-reference-evidence attachment with no line range.

Example

use dev_report::Evidence;

let e = Evidence::file_ref("source", "src/lib.rs");
assert_eq!(e.label, "source");

pub fn file_ref_lines( label: impl Into<String>, path: impl Into<String>, start: u32, end: u32, ) -> Self

Build a file-reference-evidence attachment with a [start, end] line range (1-indexed, inclusive).

Example

use dev_report::Evidence;

let e = Evidence::file_ref_lines("call_site", "src/lib.rs", 42, 47);
assert_eq!(e.label, "call_site");

pub fn kind(&self) -> EvidenceKind

Discriminator for the payload variant.

Example

use dev_report::{Evidence, EvidenceKind};

assert_eq!(Evidence::numeric("x", 1.0).kind(), EvidenceKind::Numeric);

Trait Implementations

impl Clone for Evidence

fn clone(&self) -> Evidence

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Evidence

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Evidence

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Evidence

fn eq(&self, other: &Evidence) -> 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 Evidence

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
