Struct HostError 

pub struct HostError {
    pub run: Option<usize>,
    pub code: &'static str,
    pub detail: String,
}

A refusal of spec 061 (invalid_input, 3.9), naming the run when it is one run’s, and its code.

Fields

run: Option<usize>

code: &'static str

detail: String

Implementations

impl HostError

pub fn new(code: &'static str, detail: impl Into<String>) -> HostError

pub fn at(self, run: usize) -> HostError

Trait Implementations

impl Clone for HostError

fn clone(&self) -> Self

impl Eq for HostError

impl Error for HostError

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.

impl PartialEq for HostError

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
