Struct FieldSource 

pub struct FieldSource {
    pub field: String,
    pub value: Option<String>,
    pub source: String,
    pub resolver: String,
    pub confidence: Confidence,
}

Where one field of the snapshot came from. This is what makes an inferred system debuggable: every fact can name the thing that decided it, so “why does it say that” is answered by the tool rather than by reading its source.

Fields

field: String

The field, in dotted form: services.cockpit.url, vcs.branch.

value: Option<String>

The value as it appears in the snapshot, rendered for a person; absent for a field that resolved to nothing.

source: String

What decided it: a file, a command, a compile-time constant, the cache.

resolver: String

The part of this executable that read it.

confidence: Confidence

How certain the value is.

Implementations

impl FieldSource

pub fn exact( field: impl Into<String>, value: Option<String>, source: impl Into<String>, resolver: &'static str, ) -> Self

A field resolved exactly from a named source.

pub fn cached( field: impl Into<String>, value: Option<String>, source: impl Into<String>, resolver: &'static str, ) -> Self

A field taken from an earlier full resolution rather than read now.

pub fn unknown( field: impl Into<String>, source: impl Into<String>, resolver: &'static str, ) -> Self

A field nothing could resolve; source says what was tried.

Trait Implementations

impl Clone for FieldSource

fn clone(&self) -> FieldSource

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FieldSource

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for FieldSource

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for FieldSource

impl JsonSchema for FieldSource

fn schema_name() -> Cow<'static, str>

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn inline_schema() -> bool

Whether JSON Schemas generated for this type should be included directly in parent schemas, rather than being re-used where possible using the $ref keyword.

impl PartialEq for FieldSource

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
