Struct Absent 

pub struct Absent;

The test-only absent value of confirmed-mismatch warnings.

Rust’s default codec stores no distinct absent value, unlike TypeScript’s top-level undefined. A test value type whose Serialize delegates to this marker at the top level stands for one: a warning treats it as an absent side, not as a value that failed to render, so its value field is unavailable without a loggingOutcome and the built-in difference reports the other side whole at the root pointer. serde_json renders the marker as null.

Trait Implementations

impl Clone for Absent

fn clone(&self) -> Absent

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Absent

impl Debug for Absent

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

Formats the value using the given formatter.

impl Default for Absent

fn default() -> Absent

Returns the “default value” for a type.

impl Eq for Absent

impl PartialEq for Absent

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

fn serialize<S: Serializer>(&self, serializer: S) -> Result<S::Ok, S::Error>

Serialize this value into the given Serde serializer.
