Struct Trace 

pub struct Trace {
    pub frames: Vec<TraceFrame>,
    pub omitted: Option<(usize, u32)>,
    pub refuted: Option<Refutation>,
}

What an error unwound through on its way to the top: see Ctx::take_trace.

Fields

frames: Vec<TraceFrame>

The calls it unwound through, the failing call first.

omitted: Option<(usize, u32)>

How many frames were dropped, and where among frames they were, if the trace was too long to keep.

refuted: Option<Refutation>

For a .no_match, what refuted which value.

Trait Implementations

impl Clone for Trace

fn clone(&self) -> Trace

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Trace

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

Formats the value using the given formatter.

impl Default for Trace

fn default() -> Trace

Returns the “default value” for a type.

impl PartialEq for Trace

fn eq(&self, other: &Trace) -> 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.
