Struct sval::stream::Source

pub struct Source<'a> { /* fields omitted */ }

A streamable error.

This type shouldn't be confused with sval::Error, which is used to communicate errors back to callers. The purpose of the Source type is to let streams serialize error types, that may have backtraces and other metadata.

Sources can only be created when the std feature is available, but streams can still work with them by formatting them or passing them along even in no-std environments where the Error trait isn't available.

Implementations

impl<'a> Source<'a>

pub fn new(err: &'a impl Error) -> Self

Capture an error source from a standard error.

This method is only available when the std feature is enabled.

pub fn get<'b>(&'b self) -> impl Error + 'b

Get the inner error.
