Enum Handle 

pub enum Handle {
    Column {
        name: String,
    },
    Cell {
        column: String,
        row: usize,
    },
    Range {
        column: String,
        start: usize,
        end: usize,
    },
    Dist {
        column: String,
    },
    Row {
        row: usize,
    },
}

A stable, drill-able pointer to the evidence behind a finding.

Handles are the article’s “handle-based evidence navigation”: the scan summary stays compact, and explain <handle> resolves one back to the underlying record/column/cell. Their string form is canonical and stable across runs so an agent can cache and re-query them.

Variants

Column

A whole column, by name.

Fields

name: String

Cell

A single cell at (column, row).

Fields

column: String

row: usize

Range

A contiguous row range [start, end) within a column.

Fields

column: String

start: usize

end: usize

Dist

A distribution-level finding comparing column against a baseline.

Fields

column: String

Row

A whole row, by index — for multivariate findings that span columns.

Fields

row: usize

Implementations

impl Handle

pub fn canonical(&self) -> String

Canonical wire form, e.g. cell:amount:42 or col:status.

pub fn parse(s: &str) -> Option<Handle>

Parses the canonical form. Returns None on any malformed handle so the CLI can fail cleanly rather than guess (honest absence).

Trait Implementations

impl Clone for Handle

fn clone(&self) -> Handle

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Handle

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Handle

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Handle

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

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 Handle

impl StructuralPartialEq for Handle
