Struct HostIdentityError 

#[non_exhaustive]
pub struct HostIdentityError {
    pub expected: Vec<PathBuf>,
    pub found_pid: Option<u32>,
    pub found_executable: Option<PathBuf>,
    pub reason: HostIdentityReason,
}

The process behind the endpoint is not the host the caller expected. No hello and no request frame was written to it.

Distinct from a connection error: something answered, and the OS says it is the wrong program. It is not retryable (reconnecting reaches the same program). Content-free: pids and paths only, never request data.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

expected: Vec<PathBuf>

The executables the caller said the host may be, as supplied (not canonicalised).

found_pid: Option<u32>

The pid the kernel reported for the host, when it reported one.

found_executable: Option<PathBuf>

The host’s executable, when it could be read before the refusal.

reason: HostIdentityReason

Trait Implementations

impl Eq for HostIdentityError

impl Error for HostIdentityError

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 From<HostIdentityError> for ServiceError

fn from(e: HostIdentityError) -> Self

The wire-style form of a host identity refusal: code ERROR_HOST_IDENTITY, not retryable.

impl From<HostIdentityError> for ConnectError

fn from(e: HostIdentityError) -> Self

Converts to this type from the input type.

impl PartialEq for HostIdentityError

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

Equality operator ==.

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

Inequality operator !=.
