Struct DMSCErrorChain 

pub struct DMSCErrorChain { /* private fields */ }

A chain of errors with contextual information.

Implementations

impl DMSCErrorChain

pub fn new<E>(source: E) -> Self

where E: StdError + Send + Sync + 'static,

Creates a new error chain from a source error.

pub fn with_context<E, S>(source: E, context: S) -> Self

where E: StdError + Send + Sync + 'static, S: Into<String>,

Creates a new error chain with context.

pub fn context<S>(self, context: S) -> Self

where S: Into<String>,

Adds context to the error chain.

pub fn source_error(&self) -> &(dyn StdError + Send + Sync)

Gets the source error.

pub fn get_context(&self) -> &str

Gets the context message.

pub fn previous(&self) -> Option<&DMSCErrorChain>

Gets the previous error in the chain.

pub fn chain(&self) -> DMSCErrorChainIter<'_>

Iterates through the error chain.

pub fn contains<E>(&self) -> bool

where E: StdError + Send + Sync + 'static,

Checks if this error chain contains a specific error type.

pub fn root_cause(&self) -> &(dyn StdError + Send + Sync)

Gets the root cause of the error chain.

pub fn pretty_format(&self) -> String

Formats the error chain as a pretty string.

Trait Implementations

impl Debug for DMSCErrorChain

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

Formats the value using the given formatter.

impl Display for DMSCErrorChain

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

Formats the value using the given formatter.

impl Error for DMSCErrorChain

fn source(&self) -> Option<&(dyn StdError + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.
