pub struct WithSpan<E> { /* private fields */ }
Expand description
Wrapper class for Error
, augmenting it with a list of SpanContext
s.
Implementations
sourceimpl<E> WithSpan<E>
impl<E> WithSpan<E>
sourcepub fn into_inner(self) -> E
pub fn into_inner(self) -> E
Reverse of Self::new
, discards span information and returns an inner error.
pub const fn as_inner(&self) -> &E
sourcepub fn spans(&self) -> impl Iterator<Item = &SpanContext> + ExactSizeIterator
pub fn spans(&self) -> impl Iterator<Item = &SpanContext> + ExactSizeIterator
Iterator over stored SpanContext
s.
sourcepub fn with_span<S>(self, span: Span, description: S) -> Self where
S: ToString,
pub fn with_span<S>(self, span: Span, description: S) -> Self where
S: ToString,
Add a new span with description.
sourcepub fn with_context(self, span_context: SpanContext) -> Self
pub fn with_context(self, span_context: SpanContext) -> Self
Add a SpanContext
.
sourcepub fn into_other<E2>(self) -> WithSpan<E2> where
E2: From<E>,
pub fn into_other<E2>(self) -> WithSpan<E2> where
E2: From<E>,
Convert inner error using From
.
sourcepub fn and_then<F, E2>(self, func: F) -> WithSpan<E2> where
F: FnOnce(E) -> WithSpan<E2>,
pub fn and_then<F, E2>(self, func: F) -> WithSpan<E2> where
F: FnOnce(E) -> WithSpan<E2>,
Convert inner error into another type. Joins span information contained in self
with what is returned from func
.
sourcepub fn location(&self, source: &str) -> Option<SourceLocation>
pub fn location(&self, source: &str) -> Option<SourceLocation>
Return a SourceLocation
for our first span, if we have one.
