Struct NativeError 

pub struct NativeError {
    pub step: &'static str,
    pub message: String,
    pub path: Option<PathBuf>,
}

A native startup or packaging failure.

step names the part of startup that failed so a host can say where without parsing the message, and Display is the sentence to show.

Fields

step: &'static str

Which part of startup failed: "paths", "listener", "secret", "assets", "config", "server".

message: String

The failure, phrased for a person.

path: Option<PathBuf>

The path involved, when there was one.

Implementations

impl NativeError

pub fn new(step: &'static str, message: impl Into<String>) -> Self

pub fn at( step: &'static str, path: impl AsRef<Path>, message: impl Into<String>, ) -> Self

pub fn io(step: &'static str, path: impl AsRef<Path>, error: Error) -> Self

An io::Error with the path it happened to, which the standard error does not carry and which is the only part a user can act on.

Trait Implementations

impl Debug for NativeError

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

Formats the value using the given formatter.

impl Display for NativeError

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

Formats the value using the given formatter.

impl Error for NativeError

fn source(&self) -> Option<&(dyn Error + '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.
