Struct Triad 

pub struct Triad {
    pub current: Statement,
    pub expected: Vec<Statement>,
    pub unchanged: Vec<Statement>,
    pub digest: String,
}

The person’s three statements about a bug.

Fields

current: Statement

What happens now (the symptom).

expected: Vec<Statement>

What should happen instead; at least one.

unchanged: Vec<Statement>

What must keep working as it does.

digest: String

sha256:<hex> over the normalised statements: a different digest lapses a confirmation.

Implementations

impl Triad

pub fn new( current: &str, expected: &[String], unchanged: &[String], hash: impl Fn(&[u8]) -> String, ) -> Result<Self, TriadError>

The triad of the person’s words; hash gives the hex SHA-256 of bytes (the core does no hashing itself).

Errors

An empty symptom or statement, or no Expected statement.

pub fn canonical(&self) -> String

The text the digest is over: one id<TAB>words line per statement.

pub fn statements(&self) -> impl Iterator<Item = &Statement>

Every statement: current, expected, unchanged.

pub fn statement(&self, id: &str) -> Option<&Statement>

The statement id.

pub fn cited(&self) -> Vec<String>

The Expected and Unchanged ids, the ones tests cite.

pub fn labelled(&self) -> String

The triad as labelled lines, the person’s words verbatim: what a format’s own bug step is given, and what is looked for on read-back.

pub fn title(&self) -> String

A short title: the symptom’s first sentence, at most eight words.

Trait Implementations

impl Clone for Triad

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Triad

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Triad

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for Triad

impl JsonSchema for Triad

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 Triad

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

Equality operator ==.

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

Inequality operator !=.

impl Serialize for Triad

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
