Expand description

Wrapper class for Error, augmenting it with a list of SpanContexts.

Implementations§

source§

impl<E> WithSpan<E>

source

pub const fn new(inner: E) -> Self

Create a new WithSpan from an Error, containing no spans.

source

pub fn into_inner(self) -> E

Reverse of Self::new, discards span information and returns an inner error.

source

pub const fn as_inner(&self) -> &E

source

pub fn spans(&self) -> impl Iterator<Item = &SpanContext> + ExactSizeIterator

Iterator over stored SpanContexts.

source

pub fn with_span<S>(self, span: Span, description: S) -> Selfwhere S: ToString,

Add a new span with description.

source

pub fn with_context(self, span_context: SpanContext) -> Self

Add a SpanContext.

source

pub fn into_other<E2>(self) -> WithSpan<E2>where E2: From<E>,

Convert inner error using From.

source

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.

source

pub fn location(&self, source: &str) -> Option<SourceLocation>

Return a SourceLocation for our first span, if we have one.

source

pub fn emit_to_stderr(&self, source: &str)where E: Error,

Emits a summary of the error to standard error stream.

source

pub fn emit_to_stderr_with_path(&self, source: &str, path: &str)where E: Error,

Emits a summary of the error to standard error stream.

source

pub fn emit_to_string(&self, source: &str) -> Stringwhere E: Error,

Emits a summary of the error to a string.

source

pub fn emit_to_string_with_path(&self, source: &str, path: &str) -> Stringwhere E: Error,

Emits a summary of the error to a string.
