Enum Epitaph 

pub enum Epitaph {
    Explicit(Result<(), Status>),
    PeerClosed,
}

Represents the closure condition of a FIDL channel, either via an explicit epitaph or a direct peer closure.

Variants

Explicit(Result<(), Status>)

The channel was closed with an explicit epitaph status (Ok(()) for ZX_OK success, or Err(Status) for an error).

PeerClosed

The channel was closed without an epitaph message (PEER_CLOSED).

Implementations

impl Epitaph

pub fn is_explicit(&self) -> bool

Returns true if an explicit epitaph was received or set (Explicit).

pub fn is_peer_closed(&self) -> bool

Returns true if the channel was closed without an epitaph (PEER_CLOSED) or with an explicit PEER_CLOSED epitaph.

pub fn is_ok(&self) -> bool

Returns true if an explicit ZX_OK (Ok(())) epitaph was received.

Trait Implementations

impl Clone for Epitaph

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for Epitaph

impl Debug for Epitaph

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

Formats the value using the given formatter.

impl Eq for Epitaph

impl Error for Epitaph

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<&Epitaph> for Result<(), Status>

fn from(epitaph: &Epitaph) -> Self

Converts to this type from the input type.

impl From<Epitaph> for Result<(), Status>

fn from(epitaph: Epitaph) -> Self

Converts to this type from the input type.

impl From<Result<(), Status>> for Epitaph

fn from(res: Result<(), Status>) -> Self

Converts to this type from the input type.

impl From<Status> for Epitaph

fn from(status: Status) -> Self

Converts to this type from the input type.

impl PartialEq for Epitaph

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialEq<Epitaph> for Status

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialEq<Epitaph> for Result<(), Status>

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialEq<Result<(), Status>> for Epitaph

fn eq(&self, other: &Result<(), Status>) -> bool

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialEq<Status> for Epitaph

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
